Description

Technical Field

[0001] The invention relates to a high-fluidity anti-segregation, anti-cracking, anti-seepage and durable composite material and production equipment thereof, belonging to the technical field of concrete preparation. Background Art

[0002] Concrete has a series of advantages such as high compressive strength, good durability, low cost and high plasticity. It is currently the most widely used and largest-volume building material in the civil engineering industry.

[0003] In recent years, due to the increase in concrete grades and the increased requirements for fluidity of pumped concrete, the amount of concrete cementitious materials used has greatly increased, the early hydration rate of concrete has accelerated, the early shrinkage has been large, and the hydration heat has been high; coupled with the common problems of premature demolding and insufficient maintenance conditions during construction, the problem of early cracks in concrete has almost become a "common problem" in the construction industry. The presence of cracks not only affects the appearance of concrete, but also has an adverse effect on the durability of concrete structures. The presence of internal microcracks will seriously affect the impermeability of concrete, accelerate the invasion of harmful substances and the corrosion of internal steel bars. Traditional flexible waterproofing measures not only have complex construction processes and high construction difficulty, but also their material service life is often only a few years to more than ten years, which is far from meeting the requirements of the same service life as the structure. Research on a crack-proof and impermeable material with simple construction process, low cost and the same service life as the structure is of great significance to the control and improvement of engineering quality.

[0004] At the same time, due to factors such as unreasonable mix design, unstable raw materials, large uncertainty in mixing and pouring time, and arbitrary water addition at the construction site, premixed concrete often has segregation and bleeding during actual production and pouring, which has an adverse effect on the strength and durability of concrete. Improving concrete fluidity and reducing concrete water sensitivity can effectively solve the quality control problems of concrete in the mix design, mixing, and pouring process.

[0083] Reference Figure 1 FIG. 1 is a flow chart of a method for preparing a high-fluidity anti-segregation, anti-crack, anti-permeability and durable composite material provided by an embodiment of the present invention. In this embodiment, the method for preparing a high-fluidity anti-segregation, anti-crack, anti-permeability and durable composite material comprises:

[0084] S1. Selecting an initial admixture for concrete, setting an initial mix ratio between the initial admixture and the concrete, and analyzing the compressive strength of the concrete under the initial mix ratio.

[0085] In the embodiment of the present invention, the concrete refers to the concrete composition determined by the concrete preparation method commonly used in the industry, and does not refer to the concrete entity that has been obtained, but refers to the concrete composition including the method for preparing concrete. That is to say, admixtures can be added to the preparation materials of the concrete in the future to transform the concrete. If the concrete is a prepared concrete entity, the admixture cannot transform the concrete. The initial admixture refers to an additive that solves the quality problem of concrete.

[0086] In one embodiment of the present invention, the selection of the initial admixture for concrete includes: obtaining the defect category of the concrete; identifying the defect solution category corresponding to the defect category; querying the defect solution material corresponding to the defect solution category; judging whether the reaction condition between the defect solution material and the concrete meets the reaction condition of the defect solution material; when the reaction condition between the defect solution material and the concrete meets the reaction condition of the defect solution material, aggregating the defect solution materials belonging to the same defect solution category to obtain a set of materials of the same type; and randomly combining the materials of the set of materials of the same type using the following set to obtain the initial admixture for the concrete:

[0087]

[0088] in, represents the initial admixture, Indicates the first material in the same type set Defect solving materials, Indicates the second set of materials of the same type. Defect solving materials, Indicates The first in a collection of materials of the same type Defect solving materials, Indicates the number of defect resolution categories.

[0089] Among them, the defect category refers to the category of quality defects of the concrete, including cement agglomeration, insufficient density, concrete segregation, water seepage, abnormal hardening time, harmful cracks and the like. The defect solution category refers to the category of measures for dealing with the defects corresponding to the defect category, such as the category for dealing with cement agglomeration. The defect solution materials include modified alcohol amine, magnesium oxide, saponin, sodium phosphate and polypropylene fiber, among which the cement dispersing component is modified alcohol amine, which can reduce cement agglomeration during concrete mixing, reduce the mixing resistance of fresh concrete, increase flow rate, and increase slump and expansion; the active dense expansion group is magnesium oxide, and the magnesium oxide-based expansion agent can react with water in the early stage of concrete hydration to generate expansion. The product can offset part of the early shrinkage, thereby achieving high density and reducing cracks; the surfactant component is saponin, which has good water solubility and cement adaptability. It can be added to concrete to improve the water retention of concrete and avoid concrete segregation and bleeding caused by factors such as excessive water addition and changes in material moisture content; the retarder is sodium phosphate, and the retarder dosage can be adjusted to adapt to usage scenarios with different transportation distances and pouring times; the fiber component is polypropylene fiber, which connects the matrix through bridging and friction when microcracks appear in the concrete, thereby avoiding the development of cracks, effectively reducing harmful cracks in the concrete, and improving the durability of the concrete. The reaction conditions refer to the external conditions when preparing the concrete, including parameters such as temperature and time.

[0090] In one embodiment of the present invention, setting the initial mix ratio between the initial admixture and the concrete includes: respectively obtaining the water ratio, cement ratio, sand ratio and stone ratio of water, cement, sand and stone in the concrete; querying the minimum ratio among the water ratio, the cement ratio, the sand ratio and the stone ratio; setting the initial mix ratio of the initial admixture within the ratio range lower than the minimum ratio; and determining the initial mix ratio between the initial admixture and the concrete using the initial mix ratio, the water ratio, the cement ratio, the sand ratio and the stone ratio.

[0091] Among them, the water ratio, cement ratio, sand ratio and stone ratio refer to the parameters obtained under the premise of known water, cement, sand and stone ratios in concrete. For example, if the water, cement, sand and stone ratio is 1:2:3:4, then 1 is the water ratio, 2 is the cement ratio, and the initial mix ratio refers to the mix ratio including the water ratio, the cement ratio, the sand ratio, the stone ratio and the ratio of the initial admixture.

[0092] It should be noted that the process of setting the initial ratio of the initial admixture within the ratio interval lower than the minimum ratio refers to setting any numerical value lower than the minimum ratio as the initial ratio.

[0093] Furthermore, the embodiment of the present invention analyzes the compressive strength of the concrete under the initial mix ratio, so as to utilize the performance of the initial admixture in compressive strength to select a batch of samples that can be used for subsequent comprehensive quality analysis.

[0094] The compressive strength refers to the strength grade of the concrete entity.

[0095] In one embodiment of the present invention, the analyzing the compressive strength of the concrete under the initial mix ratio includes: obtaining the concrete weight of the initial admixture and the concrete; and calculating the admixture weight of the initial admixture according to the initial mix ratio and the concrete weight using the following formula:

[0096]

[0097]

[0098]

[0099] in, represents the admixture weight of the initial admixture of the ith category, represents the concrete weight of the substance contained in the jth category of concrete, Indicates the total weight between the initial admixture and the concrete, It indicates the ratio of initial admixture under the initial mix ratio. represents the mix ratio of concrete under the initial mix ratio, n represents the number of categories in the initial admixture, m represents the number of substances contained in the concrete, express Any value in express Any value in ;

[0100] According to the weight of the concrete and the weight of the admixture, the compressive strength of the concrete is calculated using the following formula:

[0101]

[0102] in, The compressive strength of concrete. represents the admixture weight of the initial admixture of the ith category, represents the weight of concrete containing substances of the jth category, n represents the number of categories in the initial admixture, m represents the number of substances contained in the concrete, represents a constant, Indicates the weight of cement contained in concrete.

[0103] The unit of concrete weight is kg / m 3 , and the weight of concrete refers to the weight of each component in the concrete. The substances contained in the concrete and each component in the concrete are substances selected for preparing the concrete when no admixture is added, including water, cement, sand and stone. The weight of the substances contained in the concrete, that is, the water weight, cement weight, sand weight and stone weight of water, cement, sand and stone, is the weight determined in the actual scenario according to the size of the storage space of the experimental environment.

[0104] S2. Determine the final admixture of the concrete from the initial admixture using the compressive strength and determine the final mix ratio of the concrete from the initial mix ratio, wherein the final admixture includes a cement dispersant, an active densifying expansive agent, a surfactant, a retarder and fiber.

[0105] In one embodiment of the present invention, the method of determining the final admixture of the concrete from the initial admixture using the compressive strength and determining the final mix ratio of the concrete from the initial mix ratio includes: judging whether the compressive strength meets a preset compressive strength threshold; when the compressive strength meets the preset compressive strength threshold, obtaining the initial admixture corresponding to the compressive strength to obtain the final admixture; obtaining the initial mix ratio corresponding to the compressive strength to obtain the final mix ratio.

[0106] Among them, the compressive strength threshold refers to the compressive strength threshold that meets the building standards selected according to the business scenario. The final mix ratio is not just one, but multiple. In the subsequent preparation, it is necessary to select a mix ratio from multiple different final mix ratios.

[0107] S3. Calculate the amount of concrete and the amount of admixture of the final admixture according to the final mix ratio and the final admixture, generate a reference concrete of the concrete, and generate a comparison concrete of the concrete according to the amount of concrete and the amount of admixture.

[0108] It should be noted that the principle of calculating the amount of concrete and the amount of admixture of the final admixture respectively according to the final mix ratio and the final admixture is similar to the principle of calculating the admixture weight of the initial admixture mentioned above, wherein the amount of concrete and the amount of admixture refer to the substance content when preparing concrete, and the unit is kg / m 3 .

[0109] Exemplarily, the process of respectively calculating the amount of concrete and the amount of admixture of the final admixture according to the final mix ratio and the final admixture is as follows: after obtaining the final admixture, if the final mix ratio is 19:33:80:107:0.2, it is also necessary to calculate the total amount between the final admixture and the concrete based on the known amount of substances contained in the concrete, and then determine the amount of admixture by the total amount. For example, in the experimental scenario, the researchers selected 190kg / m 3 Water, 330kg / m 3 Standard cement, 800kg / m 3 Sand, 1070kg / m 3 The stone is the amount of concrete, so we can determine the ten-fold relationship between the mix ratio 19:33:80:107 and the concrete amount 190:330:800:1070, and then we can determine the ten-fold relationship between 19+33+80+107+0.2=239.2 and the actual total amount 2392, and then we can determine the proportion of 0.2 in 19:33:80:107:0.2. The product of the actual total amount of 2392 is used to obtain the amount of admixture corresponding to the ratio of 0.2. It should be noted that the substances contained in concrete are the substances selected for preparing concrete when no admixture is added, including water, cement, sand and stone. The amount of substances contained in concrete, that is, the amount of water, cement, sand and stone, is determined in the actual scenario according to the size of the storage space of the experimental environment, and this amount needs to comply with the final mix ratio of 19:33:80:107. That is to say, the part of the concrete ratio other than the admixture in the initial mix ratio and the final mix ratio is always a known and unchanged value, and the amount of concrete is the amount of each component, that is, the amount of water, cement, sand and stone.

[0110] Furthermore, in the embodiments of the present invention, the reference concrete has a similar meaning to the concrete, and the comparison concrete refers to the preparation composition of concrete modified by the amount of admixture. Therefore, both the reference concrete and the comparison concrete include strategies for preparing concrete entities rather than prepared concrete entities.

[0111] See also Figure 2, which is a schematic diagram of a reference concrete and a comparative concrete for realizing a method for preparing a high-fluidity, anti-segregation, anti-cracking, anti-permeability and durable composite material provided by an embodiment of the present invention. Figure 2 In the table, each value represents the amount of a component in concrete, and the unit of each value is kg / m 3 .

[0112] S4. Setting the mixing and pouring time of the reference concrete and the comparison concrete, and performing mixing and pouring processing on the reference concrete and the comparison concrete respectively according to the mixing and pouring time to obtain a reference processing result and a comparison processing result.

[0113] Among them, the mixing and pouring time is any time selected within the mixing and pouring time range determined according to previous preparation experience, the benchmark treatment result refers to the concrete entity obtained after mixing and pouring water, benchmark cement, sand and stone, and the comparative treatment result refers to the concrete entity obtained after mixing and pouring water, benchmark cement, sand, stone and the final admixture.

[0114] S5. Comprehensively analyze the benchmark processing results and the comparative processing results respectively to obtain benchmark analysis results and comparative analysis results. Based on the benchmark analysis results and the comparative analysis results, select the preparation admixture, preparation mix ratio and preparation time of the concrete from the final admixture, the final mix ratio and the mixing and pouring time respectively.

[0115] The embodiment of the present invention performs a comprehensive analysis on the reference processing result and the comparative processing result respectively, so as to analyze whether the quality of concrete is improved after the admixture is added.

[0116] In one embodiment of the present invention, the benchmark treatment result and the comparative treatment result are respectively comprehensively analyzed to obtain the benchmark analysis result and the comparative analysis result, including: analyzing the cement agglomeration effect of the comparative treatment result; using a preset microscopic instrument to identify the particulate matter in the comparative treatment result; and calculating the density of the comparative treatment result according to the particulate matter using the following formula:

[0119] The water seepage rate of the comparative treatment results was calculated using the following formula:

[0120]

[0121] in, represents the water seepage rate, represents the total amount of water absorbed by the comparison treatment results, W represents the amount of water used in the concrete in the comparison treatment results, represents the total mass of concrete in the comparison treatment results, represents the total mass of the cylinder and the sample, Indicates the barrel quality;

[0123] The non-uniformity refers to the ratio of the particle volume to the total volume.

[0124] Optionally, before calculating the water seepage rate of the comparative treatment result, it also includes: first wetting a volumetric covered container (inner diameter and height) with a wet cloth, loading the concrete mixture into it at one time, vibrating it on a vibration table for 20 seconds, and then gently smoothing it with a spatula, covering it to prevent moisture evaporation, the surface of the sample should be lower than the edge of the tube mouth, and the time is calculated from the start of smoothing. In the first 60 minutes, absorb the liquid and suck out the seepage water once every 10 minutes, and then absorb water every 20 minutes until there is no seepage for three consecutive times. 5 minutes before each water absorption, one side of the bottom of the tube should be raised by about to tilt the tube to facilitate water absorption. After water absorption, the tube should be gently laid flat and covered, and the water sucked out each time is injected into the measuring cylinder with a stopper, and finally the total water seepage is calculated.

[0125] In another embodiment of the present invention, the analyzing the cement agglomeration effect of the comparison treatment result includes: using a preset microscope to identify the agglomerated particles in the comparison treatment result; and calculating the uniformity of the agglomerated particles using the following formula:
