Description

Technical Field

[0001] The present invention relates to the field of building materials, and in particular to a novel green concrete production method, system, electronic equipment and computer-readable storage medium based on a stone powder replacement rate test. Background Art

[0002] At present, with the rapid development of the construction industry, the demand for concrete is increasing. However, the production process of traditional concrete consumes a lot of natural resources (such as natural sand and cement), and is accompanied by high energy consumption and high carbon emissions. This not only puts great pressure on the environment, but also exacerbates the problem of global resource depletion. Therefore, developing a green and environmentally friendly concrete production method has become a research hotspot in the field of building materials.

[0003] In this context, granite powder, as a byproduct of stone processing, is widely available and low-cost. Studies have found that the rational use of granite powder as an alternative material can significantly reduce carbon emissions in the concrete production process and improve the performance and strength of concrete to a certain extent.

[0108] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0109] The embodiment of the present application provides a new green concrete production method based on the stone powder replacement rate test.

[0110] Reference Figure 1 FIG. 1 is a flow chart of a novel green concrete production method based on a stone powder replacement rate test provided by an embodiment of the present invention. In this embodiment, the novel green concrete production method based on a stone powder replacement rate test includes:

[0111] S1. Obtain and process stone powder and concrete raw materials, wherein the concrete raw materials include: cement raw materials, sand raw materials and other raw materials.

[0112] For example, a concrete manufacturing plant plans to use granite powder or granite chips produced in the granite processing process to replace part of the cement or part of the sand in the concrete raw materials to produce a new type of green concrete. Therefore, the tester of the factory collects concrete raw materials from the warehouse for subsequent testing in order to find a suitable stone powder replacement rate, wherein one portion of concrete raw materials is used to produce a piece of concrete, and the proportions of cement, sand and concrete admixtures in the concrete raw materials have been prepared by the concrete manufacturing plant, a certain mass of cement in the concrete raw materials is cement raw materials, a certain mass of sand in the concrete raw materials is sand raw materials, and gravel and admixtures in the concrete raw materials together constitute the other raw materials. The processed stone powder set is a certain mass of granite powder and granite chips produced in the granite processing process.

[0113] S2. Using a pre-built stone powder screen, the processed stone powder set is screened to obtain a granular stone powder set and a fine stone powder set.

[0114] It should be explained that the stone powder screen is a screen used for screening and processing stone powder collection. Preferably, the pore size of the stone powder screen is 0.1 mm.

[0115] Exemplarily, the processed stone powder collection is slowly poured into the stone powder screen, and at the same time, the stone powder screen vibrates at a preset frequency, the processed stone powder collection passing through the stone powder screen is collected to obtain a fine stone powder collection, and the processed stone powder collection that does not pass through the stone powder screen is collected to obtain a granular stone powder collection.

[0116] It should be understood that a large amount of granite chips and granite powder will be generated during the granite processing, such as when cutting and grinding granite, and the particle sizes of these granite chips and granite powder are different. According to existing research, granite powder with a particle size less than 0.1 mm is usually used to replace a part of the cement raw materials in the concrete raw materials, and granite chips with a particle size greater than 0.1 mm are used to replace a part of the sand raw materials in the concrete raw materials. In addition, due to the differences in concrete raw materials and production methods, the effects of these two replacement methods on the performance and strength of concrete are also uncertain. Therefore, the embodiment of the present invention first performs a screening operation on the processed stone powder collection through a stone powder screen to separate the processed stone powder collections of different particle sizes, and then conducts a subsequent pouring reaction test to confirm the best replacement plan.

[0117] S3. Based on the preset initial replacement rate and the granular stone powder set, a sand replacement operation is performed on the concrete raw materials to obtain a first replacement raw material. Based on the initial replacement rate and the fine stone powder set, a cement replacement operation is performed on the concrete raw materials to obtain a second replacement raw material.

[0118] In detail, performing a sand replacement operation on the concrete raw material based on a preset initial replacement rate and a set of granular stone powder to obtain a first replacement raw material includes:

[0119] Weighing the sand raw material in the concrete raw material to obtain the initial sand mass;

[0120] Calculate the replacement mass according to the initial sand mass and the initial replacement rate, wherein the replacement mass is the product of the initial sand mass and the initial replacement rate;

[0121] Extracting stone powder substitute raw materials from the processed stone powder concentrate according to the substitute quality, wherein the quality of the stone powder substitute raw materials is the substitute quality;

[0122] Identifying the substitute sand in the sand raw material according to the substitute mass, wherein the mass of the substitute sand is the substitute mass;

[0124] A mixing operation is performed on the cement raw material, other raw materials, the stone powder substitute raw material and the sand substitute raw material to obtain a first substitute raw material.

[0125] It should be explained that the initial sand mass is the mass of the sand raw material. Optionally, the initial replacement rate is 5%.

[0126] Exemplarily, processed stone powder having a replacement mass is extracted from the processed stone powder as a stone powder replacement raw material, sand having a replacement mass is measured from the sand raw material as replacement sand, and then the replacement sand is removed from the sand raw material.

[0127] It should be understood that the method of obtaining the second replacement raw material by performing a cement replacement operation on the concrete raw materials based on the initial replacement rate and the fine stone powder set is the same as the method of obtaining the first replacement raw material by performing a sand replacement operation on the concrete raw materials based on the preset initial replacement rate and the granular stone powder set, and will not be repeated here.

[0128] S4. Performing a casting reaction test on the first replacement raw material and the second replacement raw material respectively to obtain a first reaction rate and a second reaction rate.

[0129] In detail, the pouring reaction test is performed on the first replacement raw material and the second replacement raw material respectively to obtain the first reaction rate and the second reaction rate, including:

[0130] performing a mixing operation on the first replacement raw material to obtain a first concrete mixture;

[0131] Confirm the hydration temperature monitoring mechanism, wherein the hydration temperature monitoring mechanism includes: a cube mold, an infrared thermometer and a thermometer, wherein the thermometer and the infrared thermometer are both fixed directly above the cube mold, and the temperature measuring direction of the infrared thermometer is aligned with the geometric center of the bottom surface of the cube mold, wherein the mold side length of the cube mold is preset;

[0132] Filling the first concrete mixture into a cube mold, and performing a leveling operation on the first concrete mixture in the cube mold to obtain a leveled mixture;

[0133] Start the infrared thermometer, take the time of starting the infrared thermometer as the starting point and record the time in real time to obtain the hydration time;

[0134] Based on the preset monitoring frequency and the started infrared thermometer, a temperature measurement operation is performed on the leveled mixture, and a reading operation is performed on the thermometer based on the monitoring frequency. When the hydration time reaches the preset hydration threshold, the infrared thermometer is turned off to obtain multiple hydration temperatures and multiple ambient temperatures, wherein the hydration temperature corresponds to the ambient temperature one by one, and the hydration temperature is obtained by performing a temperature measurement operation on the leveled mixture with the infrared thermometer, and the ambient temperature is obtained by performing a reading operation on the thermometer;

[0135] The hydration temperature rise value is calculated using multiple hydration temperatures and multiple ambient temperatures. The calculation formula is as follows:

[0136]

[0137] Among them, T react is the hydration temperature rise value, Th i is the i-th hydration temperature among multiple hydration temperatures, Te i is the ambient temperature corresponding to the i-th hydration temperature among the multiple ambient temperatures, and n is the number of hydration temperatures among the multiple hydration temperatures;

[0141] Allow the test sound wave to pass through the preliminary concrete to obtain a penetrating sound wave, use a receiver to receive the penetrating sound wave and record the time when the penetrating sound wave is received to obtain a receiving time;

[0142] The structural density is calculated using the emission time, receiving time, first curing time and mold side length. The calculation formula is as follows:

[0143]

[0144] Among them, ρ x is the structural density, t b and t a are the receiving time and the transmitting time, respectively, l0 is the side length of the mold, t0 is the first curing time, and e is a natural constant;

[0145] The first reaction rate is calculated based on the hydration temperature rise value and the structural density. The calculation formula is as follows:

[0146] v x1 =T react ×ln(1+ρ x )

[0147] Among them, v x1 is the first reaction rate, ln is the natural logarithm;

[0148] A second reaction rate is obtained based on the second replacement feedstock.

[0149] It should be understood that the mixing operation of the first replacement raw material to obtain the first concrete mixture refers to mixing the first replacement raw material with water to form a concrete mixture, and the specific amount of water added and the mixing method are determined by the production process of the concrete manufacturing plant. The first concrete mixture is a mixture formed by mixing the first replacement raw material with water and not yet solidified.

[0150] It should be explained that the hydration temperature monitoring mechanism is a device that integrates a cube mold, an infrared thermometer and a thermometer, and is used to test the hydration temperature rise value of the first concrete mixture. The cube mold is a mold with a side length equal to the side length of the mold, and is used to assist the hardening and molding of the first concrete mixture. The side length of the mold is related to the volume of the first concrete mixture. The infrared thermometer is an instrument for remotely measuring the temperature of the flat mixture surface. The main function of the thermometer is to measure the temperature of the current environment.

[0151] Exemplarily, the first concrete mixture is filled into the cube mold, and the first concrete mixture in the cube mold is smoothed with a scraper (the plane formed by the first concrete mixture on the top of the cube mold is parallel to the bottom plane of the cube mold), and the smoothed first concrete mixture in the cube mold is the leveled mixture. If the infrared thermometer is started at 10:00, then 10:00 is taken as the starting point, and when the time is 11:00, the hydration time is one hour. If the hydration threshold is 12 hours, the infrared thermometer is turned off at 22:00. If the monitoring frequency is once every 30 minutes, then at 10:30, the temperature of the surface of the leveled mixture is measured once with an infrared thermometer, and the reading of the thermometer is read. Then at 11:00, the temperature of the surface of the leveled mixture is measured again with an infrared thermometer, and the reading of the thermometer is read. This is repeated until the hydration time reaches the preset hydration threshold of 12 hours, and 24 hydration temperatures and 24 ambient temperatures are obtained. The hydration temperature is the temperature of the surface of the leveled mixture measured by the infrared thermometer, and the ambient temperature is the temperature in the environment measured by the thermometer. Since a hydration temperature and an ambient temperature are measured at the same time every hour, the hydration temperature and the ambient temperature correspond to each other in time.

[0152] It should be understood that the demoulding operation of the leveled mixture refers to separating the hardened and formed leveled mixture from the cube mold. Optionally, the leveled concrete is cured by steam curing, and the specific process of concrete curing is determined by the production process of the factory. Preferably, the first curing time is 7 days.

[0153] It should be explained that an ultrasonic sensor is a device that can emit and receive ultrasonic waves, and the main function of the transmitter is to emit ultrasonic waves, and the main function of the receiver is to receive ultrasonic waves. Test sound waves refer to ultrasonic waves emitted by ultrasonic sensors for passing through preliminary concrete. Penetrating sound waves refer to test sound waves that pass through preliminary concrete.

[0154] It should be understood that the hydration temperature rise value reflects the degree of temperature change of the leveled mixture during the cement hydration reaction. The larger the hydration temperature rise value, the greater the degree of temperature change of the leveled mixture during the cement hydration reaction.

[0155] It is understandable that when the structure of the preliminary concrete becomes denser, the propagation speed of the ultrasonic wave in the preliminary concrete will also increase, so the structural density reflects the density of the preliminary concrete. The greater the structural density, the greater the density of the preliminary concrete.

[0156] It should be understood that cement hydration is an exothermic reaction. The faster the reaction rate of cement hydration, the greater the temperature change of the leveled mixture during the cement hydration reaction. Moreover, when the reaction rate of cement hydration is faster, more hydration products will be generated in a shorter time, thereby filling the pores more quickly, thereby making the initial concrete denser. Therefore, the first reaction rate combines the hydration temperature rise value and the structural density, reflecting the average reaction rate of cement hydration of the first concrete mixture during the pouring and curing process. The greater the first reaction rate, the greater the average reaction rate of cement hydration of the first concrete mixture during the pouring and curing process.

[0157] It is understandable that the method for obtaining the second reaction rate based on the second replacement raw material is the same as the method for obtaining the first reaction rate using the first replacement raw material, and will not be repeated here.

[0158] S5. Obtain an updated concrete set based on the first reaction rate, the second reaction rate and the concrete raw materials.

[0159] It should be understood that the embodiment of the present invention compares the first reaction rate and the second reaction rate. If the first reaction rate is greater than the second reaction rate, it means that it is better to use the granular stone powder set to replace part of the sand raw materials in the concrete raw material set. Otherwise, it means that it is better to use the fine stone powder set to replace part of the cement raw materials in the concrete raw materials. Then, the concrete set is produced and updated according to the better solution.

[0160] In detail, the step of obtaining and updating the concrete set based on the first reaction rate, the second reaction rate and the concrete raw materials includes:

[0161] Obtaining a first replacement rate, a second replacement rate, a third replacement rate, and a fourth replacement rate;

[0162] comparing the first reaction rate and the second reaction rate;

[0163] If the first reaction rate is greater than the second reaction rate, obtaining a first sand raw material based on the first replacement rate, the granular stone powder set and the concrete raw material;

[0164] If the first reaction rate is less than or equal to the second reaction rate, obtaining a first cement raw material based on the first substitution rate, the fine stone powder set and the concrete raw material;

[0165] Using the first sand raw material or the first cement raw material as the first renewal raw material;

[0166] Obtaining updated leveled concrete based on the first updated raw material, and performing concrete curing on the updated leveled concrete to obtain a first test concrete;

[0167] A second test concrete is obtained based on the second replacement rate, a third test concrete is obtained based on the third replacement rate, and a fourth test concrete is obtained based on the fourth replacement rate;

[0168] The first test concrete, the second test concrete, the third test concrete and the fourth test concrete are summarized to obtain an updated concrete set.

[0169] It should be explained that the first replacement rate, the second replacement rate, the third replacement rate and the fourth replacement rate are four ratios set by the factory tester for subsequent tests. Preferably, the first replacement rate is 5%, the second replacement rate is 10%, the third replacement rate is 15%, and the fourth replacement rate is 20%.

[0170] It should be understood that the method for obtaining the first sand raw material based on the first replacement rate, the granular stone powder set and the concrete raw material is the same as the method for obtaining the first replacement raw material using the initial replacement rate, the granular stone powder set and the concrete raw material. The method for obtaining the first cement raw material based on the first replacement rate, the fine stone powder set and the concrete raw material is the same as the method for obtaining the second replacement raw material using the initial replacement rate, the fine stone powder set and the concrete raw material, and they will not be repeated here.

[0171] It is understandable that the method for obtaining the renewed leveled concrete based on the first renewed raw material is the same as the method for obtaining the leveled concrete using the first replacement raw material, and will not be described in detail herein. Preferably, the time for curing the renewed leveled concrete is 27 days.

[0172] It should be understood that the method for obtaining the second test concrete based on the second replacement rate, the method for obtaining the third test concrete based on the third replacement rate, and the method for obtaining the fourth test concrete based on the fourth replacement rate are all the same as the method for obtaining the first test concrete using the first replacement rate, and will not be repeated here.

[0173] S6. Perform a pressure strength test on the updated concrete set to obtain a pressure function, perform an environmental simulation test on the updated concrete set to obtain an environmental function, and perform a concrete loss test on the updated concrete set to obtain a loss function.

[0174] In detail, the pressure strength test is performed on the updated concrete set to obtain the pressure function, including:

[0175] Perform a weighing operation on the first test concrete in the updated concrete set to obtain an initial test mass;

[0176] Acquire a pressure time series, wherein the pressure time series includes a plurality of pressure values ​​and a plurality of time periods, and the pressure values ​​correspond to the time periods one by one, and after the pressure time series is imported into a pre-built press, a pressurizing operation is performed on the first test concrete using the press into which the pressure time series is imported, to obtain pressurized concrete;

[0177] Using a pre-built vibration table to perform a vibration operation on the compressed concrete to obtain the spalled concrete, wherein the vibration frequency and the exciting force of the vibration table are preset;

[0178] Weigh the spalled concrete to obtain the final test mass;

[0179] The first compressive strength value is calculated according to the initial test mass, the final test mass, the vibration frequency and the exciting force. The calculation formula is as follows:

[0180]

[0181] Among them, P t1 is the first compressive strength value, m x is the end test mass, m0 is the initial test mass, f0 is the vibration frequency, and F0 is the exciting force;

[0182] obtaining a second compressive strength value based on a second test concrete in the updated concrete set, obtaining a third compressive strength value based on a third test concrete in the updated concrete set, and obtaining a fourth compressive strength value based on a fourth test concrete in the updated concrete set;

[0183] The first change rate is calculated according to the first compression resistance value, the second compression resistance value, the first replacement rate and the second replacement rate. The calculation formula is as follows:

[0184]

[0185] Among them, k1 is the first rate of change, P t1 and P t2 are the first compression resistance value and the second compression resistance value, respectively, c1 and c2 are the first substitution rate and the second substitution rate, respectively;

[0186] The first change constant is calculated according to the first change rate, the first compression resistance value and the first replacement rate. The calculation formula is as follows:

[0187] a1=P t1 -k1·c1

[0188] Wherein, a1 is the first variation constant;

[0189] Based on the second pressure resistance value, the third pressure resistance value, the second replacement rate and the third replacement rate, obtain a second change rate and a second change constant; based on the third pressure resistance value, the fourth pressure resistance value, the third replacement rate and the fourth replacement rate, obtain a third change rate and a third change constant;

[0190] A pressure function is constructed according to the first change rate, the first change constant, the second change rate, the second change constant, the third change rate and the third change constant, wherein the pressure function is as follows:

[0191]

[0192] Among them, F p (x) is the pressure function, k2 and k3 are the second change rate and the third change rate respectively, a2 and a3 are the second change constant and the third change constant respectively, c3 and c4 are the third substitution rate and the fourth substitution rate respectively, and x is the independent variable.

[0193] It should be explained that the initial test mass is the mass of the first test concrete. The press is a device that can apply pressure to the first test concrete.

[0194] Exemplarily, the pressure sequence is set to (600N-5s, 1200N-10s...6000N-50s). After the pressure sequence is introduced into the press, the process of the press applying the pressurization operation to the first test concrete is as follows: in the first 5 seconds, the press applies a pressure of 600N to the first test concrete, and from 5 to 10 seconds, the press applies a pressure of 1200N to the first test concrete, and so on.

[0195] It should be understood that, under the pressure of the press, the surface and edge areas of the first test concrete will crack or even break due to the pressure exceeding the limit, and in the process of cracking and breaking, some block concrete and powdery concrete will fall off from the first test concrete, causing the quality of the first test concrete to be lost. The role of the vibration table is to separate the block concrete and powdery concrete that have not completely fallen off the surface of the first test concrete through vibration, and then quantify the ability of the first test concrete to resist pressure by comparing the termination test mass and the initial test mass.

[0196] It can be understood that the first compressive strength value reflects the ability of the first test concrete to resist pressure. The larger the first compressive strength value, the stronger the ability of the first test concrete to resist pressure.

[0197] It should be explained that the vibration table is a device that generates mechanical vibrations using the principles of electric, electro-hydraulic or piezoelectric, and the exciting force refers to the value of the force generated by the vibration table to vibrate the pressure concrete. The termination test mass refers to the mass of the spalled concrete. Optionally, the vibration frequency is 100 Hz and the exciting force is 1000N.

[0198] It should be understood that the method for obtaining the second compressive strength value based on the second test concrete in the updated concrete set, the method for obtaining the third compressive strength value based on the third test concrete in the updated concrete set, and the method for obtaining the fourth compressive strength value based on the fourth test concrete in the updated concrete set are all the same as the method for obtaining the first compressive strength value using the first test concrete in the updated concrete set, and are not described in detail here. The method for obtaining the second change rate and the second change constant based on the second compressive strength value, the third compressive strength value, the second replacement rate, and the third replacement rate, and the method for obtaining the third change rate and the third change constant based on the third compressive strength value, the fourth compressive strength value, the third replacement rate, and the fourth replacement rate are all the same as the method for obtaining the first change rate and the first change constant using the first compressive strength value, the second compressive strength value, the first replacement rate, and the second replacement rate, and are not described in detail here.

[0199] In detail, the environmental simulation test is performed on the updated concrete set to obtain the environmental function, including:

[0200] Conduct a frost resistance test on the first test concrete in the renewal concrete set to obtain the first number of freeze-thaw cycles;

[0201] A second number of freeze-thaw cycles is obtained based on the second test concrete, a third number of freeze-thaw cycles is obtained based on the third test concrete, and a fourth number of freeze-thaw cycles is obtained based on the fourth test concrete;

[0202] An environmental function is obtained based on the first freeze-thaw cycle number, the second freeze-thaw cycle number, the third freeze-thaw cycle number, and the fourth freeze-thaw cycle number.

[0203] It should be understood that the method of conducting the frost resistance test on the first test concrete in the renewed concrete set is carried out in accordance with the frost resistance test-quick freezing method in the "Standard for Test Methods of Long-term Performance and Durability of Ordinary Concrete GB / T50082-2009". And the technology of conducting the frost resistance test on the first test concrete in the renewed concrete set to obtain the first number of freeze-thaw cycles is prior art and will not be described in detail here.

[0204] Exemplarily, if the first test concrete undergoes 100 freeze-thaw cycles during the frost resistance test, then the first freeze-thaw cycle number is 100, and the first freeze-thaw cycle number reflects the frost resistance of the first test concrete. The more the first freeze-thaw cycle number, the stronger the frost resistance of the first test concrete.

[0205] It can be understood that the method for obtaining the second number of freeze-thaw cycles based on the second test concrete, the method for obtaining the third number of freeze-thaw cycles based on the third test concrete, and the method for obtaining the fourth number of freeze-thaw cycles based on the fourth test concrete are all the same as the method for obtaining the first number of freeze-thaw cycles using the first test concrete, and will not be repeated here.

[0206] In detail, the step of obtaining the environmental function based on the first freeze-thaw cycle number, the second freeze-thaw cycle number, the third freeze-thaw cycle number, and the fourth freeze-thaw cycle number includes:

[0207] The first freeze-thaw cycle number, the second freeze-thaw cycle number, the third freeze-thaw cycle number and the fourth freeze-thaw cycle number are used to obtain a first freeze-thaw change rate, a first freeze-thaw constant, a second freeze-thaw change rate, a second freeze-thaw constant, a third freeze-thaw change rate and a third freeze-thaw constant;

[0208] The environmental function is constructed using the first freeze-thaw change rate, the first freeze-thaw constant, the second freeze-thaw change rate, the second freeze-thaw constant, the third freeze-thaw change rate and the third freeze-thaw constant, where the environmental function is as follows:

[0209]

[0210] Among them, F H (x) is the environmental function, k H1 , k H2 and k H3 are the first freeze-thaw change rate, the second freeze-thaw change rate and the third freeze-thaw change rate, respectively. H1 、a H2 and a H3 They are the first freeze-thaw constant, the second freeze-thaw constant and the third freeze-thaw constant respectively.

[0211] It should be understood that the method of obtaining the first freeze-thaw change rate, the first freeze-thaw constant, the second freeze-thaw change rate, the second freeze-thaw constant, the third freeze-thaw change rate and the third freeze-thaw constant using the first freeze-thaw cycle number, the second freeze-thaw cycle number, the third freeze-thaw cycle number and the fourth freeze-thaw cycle number is the same as the method of obtaining the first change rate, the first change constant, the second change rate, the second change constant, the third change rate and the third change constant using the first pressure resistance value, the second pressure resistance value, the third pressure resistance value and the fourth pressure resistance value, and the method of constructing the environmental function using the first freeze-thaw change rate, the first freeze-thaw constant, the second freeze-thaw change rate, the second freeze-thaw constant, the third freeze-thaw change rate and the third freeze-thaw constant is the same as the method of constructing the pressure function using the first change rate, the first change constant, the second change rate, the second change constant, the third change rate and the third change constant, which will not be repeated here.

[0212] In detail, the concrete loss test is performed on the updated concrete set to obtain the loss function, including:

[0213] Perform a cutting operation on the first test concrete in the updated concrete set to obtain cut concrete;

[0214] Weigh the cut concrete to obtain the initial wear mass;

[0215] Start the pre-built abrasion tester, wherein the abrasion tester includes: a pressurizing unit, a rotating disk and a grinding wheel;

[0216] The cut concrete is fixed on the rotating disk of the abrasion tester, and a pressurizing unit is used to pressurize the cut concrete fixed on the rotating disk of the abrasion tester to obtain fixed concrete, wherein the pressurizing pressure of the pressurizing unit to pressurize the cut concrete fixed on the rotating disk of the abrasion tester is preset;

[0217] The grinding wheel and the rotating disk in the abrasion tester are used to perform a rotational friction operation on the fixed concrete to obtain the worn concrete, wherein the friction speed and the friction time of the grinding wheel and the rotating disk in the abrasion tester performing the rotational friction operation on the fixed concrete are preset;

[0218] Weighing the worn concrete to obtain the final wear mass;

[0219] The first wear resistance is calculated based on the initial wear mass, final wear mass, pressurization pressure, friction speed and friction time. The calculation formula is as follows:

[0220]

[0221] Among them, S1 is the first wear resistance, m a and m b are the initial wear mass and the final wear mass, F s is the pressure, v s is the friction speed, t s for friction time;

[0222] obtaining a second wear resistance based on the second test concrete, obtaining a third wear resistance based on the third test concrete, and obtaining a fourth wear resistance based on the fourth test concrete;

[0223] A loss function is obtained based on the first wear resistance, the second wear resistance, the third wear resistance, and the fourth wear resistance.

[0224] It should be explained that when the cutting operation is performed on the first test concrete in the updated concrete set to obtain the cut concrete, the shape of the cut concrete is a cube, and the cutting side length of the cut concrete is preset, and the cutting side length must be less than the diameter of the turntable of the abrasion tester. The initial wear mass is the mass of the cut concrete. The abrasion tester is an instrument that can perform rotational friction on the cut concrete to measure the first wear resistance of the cut concrete, and the abrasion tester includes a pressurizing unit, a turntable and a grinding wheel. The main function of the pressurizing unit is to apply pressure to the cut concrete fixed on the turntable of the abrasion tester, thereby adjusting the friction force of the abrasion tester during the rotational friction process. The turntable is a rotatable metal disc in the abrasion tester. By fixing the cut concrete on the turntable of the abrasion tester, the cut concrete rotates with the rotation of the turntable. The grinding wheel is made of high-hardness abrasive and is used to rub the fixed concrete. Optionally, the pressurizing pressure is 10N. The pressurizing operation performed on the cut concrete fixed on the turntable of the abrasion tester using the pressurizing unit refers to applying pressure to the cut concrete fixed on the turntable of the abrasion tester using the pressurizing unit. The use of the grinding wheel and the turntable in the abrasion tester to perform a rotational friction operation on the fixed concrete means: the turntable in the abrasion tester is rotated at a friction speed to drive the fixed concrete to rotate, and the grinding wheel of the abrasion tester rubs the fixed concrete. The friction time refers to the time for the grinding wheel and the turntable in the abrasion tester to perform a rotational friction operation on the fixed concrete. The end wear quality refers to the quality of the worn concrete. Optionally, the friction speed is 90r / min and the friction time is 1 minute.

[0225] It can be understood that the first wear resistance reflects the wear resistance of the first test concrete. The greater the first wear resistance, the stronger the wear resistance of the first test concrete.

[0226] In detail, the acquiring of the loss function based on the first loss cycle number, the second loss cycle number, the third loss cycle number, and the fourth loss cycle number includes:

[0227] Obtaining a first loss change rate, a first loss constant, a second loss change rate, a second loss constant, a third loss change rate, and a third loss constant using a first loss cycle number, a second loss cycle number, a third loss cycle number, and a fourth loss cycle number;

[0228] A loss function is constructed using the first loss change rate, the first loss constant, the second loss change rate, the second loss constant, the third loss change rate, and the third loss constant, wherein the loss function is as follows:

[0229]

[0230] Among them, F s (x) is the loss function, k s1 , k s2 and ks3 are the first loss change rate, the second loss change rate and the third loss change rate respectively, a s1 、a s2 and a s3 They are the first loss constant, the second loss constant and the third loss constant respectively.

[0231] It should be understood that the method of obtaining the first loss change rate, the first loss constant, the second loss change rate, the second loss constant, the third loss change rate and the third loss constant by using the first loss cycle number, the second loss cycle number, the third loss cycle number and the fourth loss cycle number is the same as the method of obtaining the first change rate, the first change constant, the second change rate, the second change constant, the third change rate and the third change constant by using the first pressure resistance value, the second pressure resistance value, the third pressure resistance value and the fourth pressure resistance value, and the method of constructing a loss function by using the first loss change rate, the first loss constant, the second loss change rate, the second loss constant, the third loss change rate and the third loss constant is the same as the method of constructing a pressure function by using the first change rate, the first change constant, the second change rate, the second change constant, the third change rate and the third change constant, which will not be repeated here.

[0232] S7. Use the pressure function, environmental function and loss function to construct a comprehensive performance function, identify the target doping raw materials based on the comprehensive performance function, use the target doping raw materials to produce new concrete, and complete the production of new green concrete.

[0233] In detail, the comprehensive performance function is as follows:

[0234] F0(x)=F p (x)·F H (x)·F s (x)

[0235] Among them, F0(x) is the comprehensive performance function, F H (x) is the environmental function, F s (x) is the loss function.

[0236] In detail, the step of identifying the target doping raw material based on the comprehensive performance function includes:

[0237] A comprehensive performance curve is drawn on a pre-constructed plane rectangular coordinate system according to the comprehensive performance function, wherein the comprehensive performance curve includes: a plurality of coordinate points;

[0238] The highest performance point is determined based on the comprehensive performance curve, wherein the highest performance point is the coordinate point with the largest ordinate on the plane rectangular coordinate system of the comprehensive performance curve;

[0239] Determine the target replacement rate based on the highest performance point, where the target replacement rate is the value of the horizontal coordinate corresponding to the highest performance point on the plane rectangular coordinate system;

[0240] A target doping raw material is obtained based on the target substitution rate.

[0241] It should be explained that a plurality of coordinate points together constitute the comprehensive performance curve on the plane rectangular coordinate system. The method for obtaining the target doping raw material based on the target substitution rate is the same as the method for obtaining the first renewal raw material using the first substitution rate, and will not be repeated here. The method for producing a new concrete using the target doping raw material is the same as the method for obtaining the first test concrete using the first renewal raw material, and will not be repeated here.

[0242] It should be understood that since adding stone powder to concrete raw materials will affect the concrete's ability to resist pressure, antifreeze and wear resistance at the same time, and the concrete's ability to resist pressure, antifreeze and wear resistance will not increase or decrease at the same time with the change of stone powder replacement rate, it may happen that with the increase of stone powder replacement rate, the concrete's ability to resist pressure becomes stronger, while its ability to resist freezing becomes weaker. Therefore, the embodiment of the present invention constructs a comprehensive performance function, comprehensively considers the concrete's ability to resist pressure, antifreeze and wear resistance, and uses the comprehensive performance function to seek the optimal solution of concrete performance, thereby determining the optimal target replacement rate, and then producing a new type of concrete.

[0243] The present invention is to solve the problem described in the background technology. The present invention obtains a processed stone powder set and concrete raw materials, wherein the concrete raw materials include: cement raw materials, sand raw materials and other raw materials. It can be seen that the embodiment of the present invention obtains concrete raw materials and a processed stone powder set, thereby providing materials for subsequent experiments, and then uses a pre-constructed stone powder screen to perform a screening operation on the processed stone powder set to obtain a granular stone powder set and a fine stone powder set. It can be seen that the embodiment of the present invention screens the processed stone powder set through the stone powder screen to distinguish processed stone powders of different particle sizes, thereby facilitating the subsequent use of processed stone powder with a larger particle size to replace the sand in the concrete raw materials, and using processed stone powder with a smaller particle size Small processed stone powder replaces cement in concrete raw materials to improve the similarity between the substitute and sand or cement, so that the performance of the replaced concrete raw materials is better. Based on the preset initial replacement rate and the granular stone powder set, the sand replacement operation is performed on the concrete raw materials to obtain the first replacement raw material. Based on the initial replacement rate and the fine stone powder set, the cement replacement operation is performed on the concrete raw materials to obtain the second replacement raw material. The first replacement raw material and the second replacement raw material are respectively subjected to casting reaction tests to obtain the first reaction rate and the second reaction rate. Based on the first reaction rate, the second reaction rate and the concrete raw materials, an updated concrete set is obtained. It can be seen that the embodiment of the present invention is through By performing casting reaction tests on the first replacement raw material and the second replacement raw material after replacement, respectively, the first reaction rate and the second reaction rate of the two replacement schemes are compared, and the best replacement scheme is confirmed in the two replacement schemes of replacing cement and replacing sand, and then the updated concrete set is produced through the confirmed scheme, and the pressure strength test is performed on the updated concrete set to obtain the pressure function, the environmental simulation test is performed on the updated concrete set to obtain the environmental function, and the concrete loss test is performed on the updated concrete set to obtain the loss function. It can be seen that the embodiment of the present invention performs pressure strength test, environmental simulation test and concrete loss test on the updated concrete set, respectively, and uses scientific tests to analyze the strength and performance of the updated concrete set, thereby improving the scientificity of selecting the stone powder replacement rate, constructing a comprehensive performance function using the pressure function, the environmental function and the loss function, confirming the target doping raw material based on the comprehensive performance function, and producing the new concrete using the target doping raw material to complete the production of the new green concrete. It can be seen that the embodiment of the present invention constructs a comprehensive performance function, thereby determining the optimal solution of the stone powder replacement rate through the maximum value of the comprehensive performance function, and then using the confirmed stone powder replacement rate to produce the new concrete, thereby improving the accuracy of selecting the stone powder replacement rate. Therefore, the present invention can improve the accuracy and scientificity when selecting the stone powder replacement rate.

[0244] like Figure 2 , which is a functional module diagram of a new green concrete production system based on a stone powder replacement rate test provided by an embodiment of the present invention.

[0245] The new green concrete production system 100 based on the stone powder replacement rate test of the present invention can be installed in an electronic device. According to the functions to be implemented, the new green concrete production system 100 based on the stone powder replacement rate test can include a stone powder processing screening module 101, a stone powder raw material replacement module 102, a concrete performance test module 103 and a performance function construction module 104.

[0250] In detail, each module in the novel green concrete production system 100 based on the stone powder replacement rate test in the embodiment of the present invention is used in the same manner as above. Figure 1 The new green concrete production method based on stone powder replacement rate test described in the invention has the same technical means and can produce the same technical effects, so I will not go into details here.
