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] With the rapid development of the construction industry, the demand for concrete is increasing. However, the production of traditional concrete consumes a large amount of natural resources (such as natural sand and cement), and is accompanied by high energy consumption and carbon emissions. This not only puts tremendous 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 dust, a byproduct of stone processing, is widely available and low-cost. Research has found that the rational use of granite dust as an alternative material can significantly reduce carbon emissions during concrete production and improve concrete's performance and strength.

[0004] While existing stone dust replacement methods can produce new green concrete, determining the specific replacement scheme and stone dust replacement ratio often relies on human judgment and lacks scientific analysis based on actual performance.

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

[0109] The embodiment of the present application provides a new green concrete production method based on a stone powder replacement rate test. The execution subject of the new green concrete production method based on the stone powder replacement rate test includes but is not limited to at least one of the electronic devices such as a server and a terminal that can be configured to execute the method provided by the embodiment of the present application.

[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 according to 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. Obtaining a collection of processed 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 generated during granite processing to replace part of the cement or sand in the concrete raw materials to produce a new type of green concrete. Therefore, the plant's testers collect concrete raw materials from the warehouse for subsequent testing to find an appropriate stone powder replacement ratio. Here, one unit of concrete raw materials is used to produce one block of concrete, and the proportions of cement, sand, and concrete admixtures in the concrete raw materials have been determined by the concrete manufacturing plant. A certain mass of cement in the concrete raw materials is the cement raw material, a certain mass of sand in the concrete raw materials is the sand raw material, and the gravel and admixtures in the concrete raw materials together constitute the other raw materials. The processed stone powder is a certain mass of granite powder and granite chips generated during the granite processing process.

[0113] S2. Using a pre-built stone powder screen, a screening operation is performed on the processed stone powder set 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. At the same time, the stone powder screen vibrates at a preset frequency. The processed stone powder collection that passes 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 during granite processing, such as when cutting and grinding granite, a large amount of granite debris and granite powder will be generated, and the particle sizes of these granite debris and granite powder vary. According to existing research, granite powder with a particle size of less than 0.1 mm is usually used to replace a portion of the cement raw materials in concrete raw materials, while granite debris with a particle size greater than 0.1 mm is used to replace a portion of the sand raw materials in concrete raw materials. Moreover, 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 optimal replacement scheme.

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

[0118] Specifically, 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 materials in the concrete raw materials to obtain the initial sand mass;

[0120] Calculate the replacement mass based on the initial sand mass and the initial replacement rate, where 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 according to the substitute quality, wherein the quality of the stone powder substitute raw materials is the substitute quality;

[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 with a replacement mass is extracted from the processed stone powder as a stone powder replacement raw material, sand with 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 performing a cement replacement operation on concrete raw materials based on the initial replacement rate and the fine stone powder set to obtain the second replacement raw material is the same as the method of performing a sand replacement operation on concrete raw materials based on the preset initial replacement rate and the granular stone powder set to obtain the first replacement raw material, and will not be repeated here.

[0128] S4. Performing a pouring 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.

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

[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 mixing the first replacement raw material to obtain the first concrete mixture refers to adding water to the first replacement raw material to form a concrete mixture. 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 of the first replacement raw material and water that has not yet set and hardened.

[0150] It should be explained that the hydration temperature monitoring mechanism integrates a cube mold, an infrared thermometer, and a thermometer to measure the hydration temperature rise of the first concrete mixture. The cube mold, with a side length equal to the mold's side length, is used to assist in the hardening and forming of the first concrete mixture. The mold side length 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 thermometer's primary function is to measure the current ambient temperature.

[0151] For example, a first concrete mixture is filled into a cube mold and then smoothed using 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). The smoothed first concrete mixture in the cube mold is called a leveled mixture. If the infrared thermometer is activated at 10:00, then the hydration time is one hour starting at 10:00. If the hydration threshold is 12 hours, then 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 smooth mixture is measured once using an infrared thermometer and the reading of the thermometer is read. Then, at 11:00, the temperature of the surface of the smooth mixture is measured again using an infrared thermometer and the reading of the thermometer is read. This process is repeated until the hydration time reaches the preset hydration threshold of 12 hours, resulting in 24 hydration temperatures and 24 ambient temperatures. The hydration temperature is the temperature of the surface of the smooth mixture measured by the infrared thermometer, and the ambient temperature is the temperature of the environment measured by the thermometer. Since a hydration temperature and an ambient temperature are measured simultaneously every hour, the hydration temperature and the ambient temperature correspond to each other in time.

[0152] It should be understood that demolding the smoothed mix refers to separating the hardened, smoothed mix from the cube mold. Optionally, steam curing is used to cure the smoothed concrete, with the specific curing process determined by the factory's production process. Preferably, the first curing period is 7 days.

[0153] It should be explained that an ultrasonic sensor is a device that can both transmit and receive ultrasonic waves. The transmitter's primary function is to transmit ultrasonic waves, while the receiver's primary function is to receive them. Test sound waves refer to the ultrasonic waves emitted by the ultrasonic sensor that are intended to penetrate the preliminary concrete. Penetrating sound waves refer to the test sound waves that penetrate the 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 cement hydration reaction rate, the greater the temperature change of the leveled mixture during the cement hydration reaction. Moreover, the faster the cement hydration reaction rate, the 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, in the embodiment of the present invention, by comparing the first reaction rate and the second reaction rate, if the first reaction rate is greater than the second reaction rate, it means that the solution of using the granular stone powder set to replace part of the sand raw material in the concrete raw material set is better. Otherwise, it means that the solution of using the fine stone powder set to replace part of the cement raw material in the concrete raw material set is better. Then, the updated concrete set is produced 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 materials;

[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 noted that the first, second, third, and fourth replacement rates are four ratios set by factory testers for subsequent testing. 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 of 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 of obtaining the first replacement raw material using the initial replacement rate, the granular stone powder set and the concrete raw material. The method of 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 of obtaining the second replacement raw material using the initial replacement rate, the fine stone powder set and the concrete raw material. They will not be repeated here.

[0171] It is understood 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] Weighing the first test concrete in the updated concrete set to obtain an initial test mass;

[0176] Obtaining 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 in a one-to-one manner, importing the pressure time series into a pre-built press, and performing a pressurizing operation on the first test concrete using the press imported with the pressure time series to obtain pressurized concrete;

[0177] Performing a vibration operation on the compressed concrete using a pre-built vibration table to obtain spalled concrete, wherein the vibration frequency and 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 based on the initial test mass, final test mass, vibration frequency and exciting force. The calculation formula is as follows:

[0180]

[0181] Among them, P t1 is the first compressive strength value, m x is the ending 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 based on 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 and second compression resistance values, c1 and c2 are the first and second replacement rates, respectively;

[0186] The first change constant is calculated based on the first change rate, the first compressive strength 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] Obtain a second change rate and a second change constant based on the second pressure resistance value, the third pressure resistance value, the second replacement rate, and the third replacement rate; and obtain a third change rate and a third change constant based on the third pressure resistance value, the fourth pressure resistance value, the third replacement rate, and the fourth replacement rate;

[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] For example, the pressure sequence is set to (600N-5s, 1200N-10s...6000N-50s). After the pressure sequence is introduced into the press, the press performs the pressurization operation on the first test concrete as follows: in the first 5 seconds, the press applies a pressure of 600N to the first test concrete; 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 blocky concrete and powdery concrete will fall off from the first test concrete, thereby causing a loss in the quality of the first test concrete. The role of the vibration table is to separate the blocky 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 final test mass with 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 greater the first compressive strength value, the stronger the ability of the first test concrete to resist pressure.

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

[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 for conducting the frost resistance test on the first test concrete in the renewed concrete set was conducted in accordance with the frost resistance test - rapid freezing method specified in the "Standard for Testing Methods for Long-term Properties and Durability of Ordinary Concrete GB / T50082-2009." Furthermore, the technology for 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 further described here.

[0204] For example, 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 cycles, the stronger the frost resistance of the first test concrete.

[0205] It is understandable 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] Obtaining 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 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;

[0208] An 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. 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] performing 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 abraser, which includes: a pressurizing unit, a rotating disk, and a grinding wheel;

[0216] Fixing the cut concrete on the turntable of the abrasion tester, and performing a pressurizing operation on the cut concrete fixed on the turntable of the abrasion tester using a pressurizing unit to obtain fixed concrete, wherein the pressurizing pressure of the pressurizing unit for performing the pressurizing operation on the cut concrete fixed on the turntable 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 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 pressurized pressure, v s is the friction speed, t s is the 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, the cut concrete is shaped like a cube, with a predetermined side length that is less than the diameter of the abraser's rotating disc. The initial wear mass is the mass of the cut concrete. The abraser is an instrument that performs rotational friction on the cut concrete to measure its initial wear resistance. The abraser comprises a pressure unit, a rotating disc, and a grinding wheel. The pressure unit primarily applies pressure to the cut concrete fixed to the abraser's rotating disc, thereby adjusting the friction force during the rotational friction process. The rotating disc is a rotating metal disc in the abraser. By attaching the cut concrete to the abraser's rotating disc, the cut concrete rotates with the disc. The grinding wheel is made of high-hardness abrasive and is used to rub the fixed concrete. Optionally, the applied pressure is 10N. Using the pressure unit to apply pressure to the cut concrete fixed to the abraser's rotating disc refers to applying pressure to the cut concrete fixed to the abraser's rotating disc using the pressure unit. The abrasive tester's grinding wheel and rotating disk performing a rotational friction operation on the fixed concrete refers to rotating the rotating disk at a friction speed, thereby driving the fixed concrete to rotate, while simultaneously causing the grinding wheel of the abrasive tester to rub the fixed concrete. The friction time refers to the time the grinding wheel and rotating disk of the abrasive tester perform the rotational friction operation on the fixed concrete. The final wear mass refers to the mass of the worn concrete. Optionally, the friction speed is 90 r / 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 the first loss cycle number, the second loss cycle number, the third loss cycle number, and the 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, 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 the 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 the 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, and they 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] Determine the highest performance point based on the comprehensive performance curve, where 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 noted that the multiple coordinate points on the rectangular coordinate system together constitute the comprehensive performance curve. 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 renewed raw material using the first substitution rate and is not further described here. The method for producing the new concrete using the target doping raw material is the same as the method for obtaining the first test concrete using the first renewed raw material and is not further described here.

[0242] It should be understood that since the addition of stone powder to concrete raw materials will simultaneously affect the concrete's ability to resist pressure, antifreeze and wear resistance, and the concrete's ability to resist pressure, antifreeze and wear resistance will not increase or decrease simultaneously with the change of the stone powder replacement rate, it may happen that as the stone powder replacement rate increases, the concrete's ability to resist pressure becomes stronger, while its ability to resist frost 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 for concrete performance, thereby determining the optimal target replacement rate and 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 provides materials for subsequent experiments by obtaining concrete raw materials and processed stone powder sets, and then uses a pre-built 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 larger particle sizes to replace the sand in the concrete raw materials, and using processed stone powder with smaller particle sizes. 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 pouring 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 conducting pouring reaction tests on the first and second replacement raw materials after replacement, the first and second reaction rates of the two replacement schemes are compared, and the optimal replacement scheme is identified among the two replacement schemes of replacing cement and replacing sand. Then, an updated concrete set is produced using the confirmed scheme. A pressure strength test is conducted on the updated concrete set to obtain a pressure function. An environmental simulation test is conducted on the updated concrete set to obtain an environmental function. A concrete loss test is conducted on the updated concrete set to obtain a loss function. It can be seen that the embodiment of the present invention conducts pressure strength tests, environmental simulation tests, and concrete loss tests on the updated concrete set, using scientific experiments to analyze the strength and performance of the updated concrete set, thereby improving the scientific nature of the selection of the stone powder replacement rate. The pressure function, environmental function, and loss function are used to construct a comprehensive performance function. Based on the comprehensive performance function, the target doping raw material is identified. The target doping raw material is used to produce the new concrete, completing 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 for 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 the selection of 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 one embodiment of the present invention.

[0245] The new green concrete production system 100 based on the stone dust replacement rate test described in the present invention can be installed in an electronic device. Depending on the functionality implemented, the new green concrete production system 100 based on the stone dust replacement rate test can include a stone dust processing and screening module 101, a stone dust raw material replacement module 102, a concrete performance testing module 103, and a performance function construction module 104. A module, also referred to as a unit, is a series of computer program segments that can be executed by an electronic device processor and perform a fixed function. These are stored in the electronic device's memory.

[0246] The processed stone powder screening module 101 is used to obtain 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, and perform a screening operation on the processed stone powder set using a pre-built stone powder screen to obtain a granular stone powder set and a fine stone powder set;

[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 adopts the same Figure 1 The new green concrete production method based on the stone powder replacement rate test described in the previous section uses the same technical means and can produce the same technical effects, so I will not go into details here.

[0251] like Figure 3 , which is a structural diagram of an electronic device for implementing a new green concrete production method based on a stone powder replacement rate test provided by an embodiment of the present invention.
