Description

Technical Field

[0001] This application relates to the field of building engineering, and in particular to a low-carbon concrete mix design method, a smart terminal, and a storage medium. Background Technology

[0002] Concrete mix proportion refers to the ratio and amount of water, cementitious materials, fine aggregate, and coarse aggregate in concrete. The concrete mix proportion determines the strength, durability, and quality of concrete, and has a significant impact on concrete production and construction.

[0003] Currently, the main methods for designing concrete mix proportions are experimental methods and theoretical analysis methods. Experimental methods typically require technicians to conduct numerous tests to prepare the concrete, which is time-consuming and relies heavily on the experience of the technicians, lacking applicability. Therefore, theoretical analysis methods are currently the primary method used for designing concrete mix proportions.

[0004] Using theoretical analysis to design concrete mix proportions can more quickly produce concrete mix proportions that meet performance parameter requirements. However, existing theoretical analysis methods generally only consider the impact of aggregate dosage on concrete performance indicators during the concrete mix proportion design process, resulting in a large amount of cementitious materials in the determined concrete mix proportion. Since cementitious materials continuously release a large amount of carbon dioxide during drying and curing, the applicant believes that the existing theoretical analysis method for designing concrete mix proportions is prone to causing the carbon emissions of concrete to exceed the standard. Summary of the Invention

[0005] In order to effectively reduce the carbon emissions of concrete, this application provides a low-carbon concrete mix design method, a smart terminal, and a storage medium.

[0006] Firstly, the low-carbon concrete mix design method provided in this application adopts the following technical solution: A method for designing the mix proportions of low-carbon concrete, comprising: Obtain the concrete type and the corresponding concrete materials and concrete mix proportions, and estimate the initial carbon emissions of the concrete based on the concrete materials and concrete mix proportions; Determine whether the initial carbon emissions meet the preset carbon emission standard based on the type of concrete. If the initial carbon emissions do not meet the carbon emission standard, the concrete mix proportion is changed according to the carbon emission standard to obtain the test mix proportion; The test mix ratio was simulated; The test mix ratio is determined based on preset simulation conditions to determine whether it passes the simulation. If the simulation is successful, the test mix ratio will be used as the final mix ratio.

[0007] By adopting the above technical solution, the initial carbon emissions of concrete are first estimated, and the mix proportion of concrete is adjusted according to the carbon emission standard to obtain the test mix proportion. Then, the test mix proportion is simulated, and the simulated test mix proportion is the final mix proportion. This makes it easier to control the carbon emissions of concrete within the carbon emission standard and effectively reduce the carbon emissions of concrete.

[0008] Optionally, estimating the initial carbon emissions of the concrete based on the concrete materials and the concrete mix proportions includes: The carbon emissions per unit volume of each concrete material are obtained from a pre-set concrete material carbon emission statistics database. Based on the preset total concrete volume and the concrete mix proportion, the initial volume of each concrete material is calculated; based on the initial volume of each concrete material and the carbon emission per unit volume of each concrete material, the initial carbon emission of the total concrete volume is calculated.

[0009] By adopting the above technical solution, the initial carbon emissions of concrete can be estimated based on the initial volume of each type of concrete material, which helps to improve the accuracy of the initial carbon emissions calculation.

[0010] Optionally, determining whether the initial carbon emissions meet the preset carbon emission standard based on the concrete type includes: Obtain the standard carbon emission corresponding to the concrete type from the preset carbon emission standard database; Determine whether the initial carbon emissions are greater than the standard carbon emissions; If the value is greater than the initial carbon emission level, it is determined that the initial carbon emission level does not meet the carbon emission standard. If it is not greater than, the initial carbon emissions are determined to meet the carbon emission standard.

[0011] By adopting the above technical solution, the initial carbon emissions are compared with the standard carbon emissions to determine whether the initial carbon emissions meet the carbon emission standards, thereby facilitating the subsequent adjustment of the concrete mix proportions.

[0012] Optionally, if the initial carbon emissions do not meet the carbon emission standard, the concrete mix proportion is modified according to the carbon emission standard to obtain a test mix proportion, including: If the initial carbon emissions do not meet the carbon emission standard, the concrete strength grade is obtained according to the concrete type; a new concrete mix proportion is generated according to the concrete strength grade and the carbon emission standard. Determine whether the new concrete mix proportion meets the preset concrete engineering design standards; If the conditions are met, the new concrete mix proportion shall be used as the test mix proportion.

[0013] By adopting the above technical solution, if the initial carbon emissions do not meet the carbon emission standards, a new concrete mix proportion is first generated based on the concrete strength grade and the carbon emission standards. After the new concrete mix proportion meets the concrete engineering design standards, it is used as the test mix proportion. This allows the concrete to meet both the concrete engineering design standards and the carbon emission standards, thereby effectively reducing the carbon emissions of the concrete while ensuring its quality.

[0014] Optionally, generating a new concrete mix proportion based on the concrete strength grade and the carbon emission standard includes: Based on the concrete strength grade, select concrete test materials that conform to the concrete strength grade; the concrete test materials include test cementitious materials; Based on the statistical database of carbon emissions of concrete materials, the target test cementitious material with the largest carbon emissions per unit volume among all the tested cementitious materials is obtained. Obtain alternative test cementitious materials whose carbon emissions per unit volume are less than a preset threshold value from the concrete material carbon emission statistics database. The proportion of the alternative test cementitious material in the concrete material is obtained according to the proportion of the target test cementitious material in the concrete material, and the alternative test cementitious material is used to replace the target test cementitious material to obtain a new concrete test material; The test carbon emissions of the new concrete test material are calculated based on the concrete material carbon emission statistics database. If the tested carbon emissions are equal to the standard carbon emissions, the mix proportion of the new concrete test material shall be used as the mix proportion of the new concrete.

[0015] By adopting the above technical solution, the appropriate concrete testing materials can be selected according to the concrete strength grade, which can effectively ensure the quality of concrete materials. When the tested carbon emissions are equal to the standard carbon emissions, the mix proportion of the new concrete testing materials can be used as the mix proportion of the new concrete, which can effectively reduce the carbon emissions of concrete while ensuring the quality of concrete.

[0016] Optionally, the method further includes: If the tested carbon emissions are less than the standard carbon emissions, the alternative test cementitious material and the target test cementitious material are mixed in different mixing ratios to form a mixed test cementitious material. Calculate the mixed carbon emissions of the mixed test cementitious materials corresponding to each of the mixing ratios, and screen out the mixed carbon emissions that are greater than the preset cementitious material carbon emissions, and obtain the target mixed carbon emissions that are less than or equal to the cementitious material carbon emissions. The minimum carbon emission is obtained from all the target mixed carbon emission amounts, and the mixing ratio of the alternative test cementitious material and the target test cementitious material corresponding to the minimum carbon emission amount is taken as the target mixing ratio. Based on the target mixing ratio, the mix proportion of the concrete test material is obtained, and the mix proportion of the concrete test material is used as the new concrete mix proportion.

[0017] By adopting the above technical solution, when the tested carbon emissions are less than the standard carbon emissions, the mix proportion of the concrete test materials is obtained according to the target mixing ratio, which effectively ensures the minimum carbon emissions of concrete and thus effectively reduces the carbon emissions of concrete.

[0018] Optionally, the concrete material includes cementitious materials; the simulation conditions include the standard proportion of the cementitious materials in the concrete material; The step of determining whether the test mix ratio passes simulation based on preset simulation conditions includes: Obtain the test proportion of the cementitious material in the test mix proportion; If the test ratio is less than or equal to the standard ratio, the test ratio is deemed to have passed the simulation.

[0019] By adopting the above technical solution, the test mix proportion is determined to pass the simulation when it is less than the standard mix proportion, thereby effectively ensuring the amount of cementitious materials in the concrete mix proportion, effectively reducing the amount of cementitious materials in the concrete, and thus effectively controlling the cost of concrete.

[0020] Optionally, the simulation conditions also include the standard concrete cost of the concrete material; The step of determining whether the test mix ratio passes the simulation based on preset simulation conditions further includes: Obtain the concrete cost of the concrete material corresponding to the test mix proportion; If the cost of the concrete is less than or equal to the cost of the standard concrete, the test mix proportion is deemed to have passed the simulation.

[0021] By adopting the above technical solution, when the concrete cost is less than or equal to the standard concrete cost, the test mix proportion is determined through simulation, thus effectively controlling the concrete cost.

[0022] Secondly, the smart terminal provided in this application adopts the following technical solution: A smart terminal includes a memory, a processor, and a computer program stored in the memory and capable of running on the processor. When the processor loads and executes the computer program, it employs the aforementioned low-carbon concrete mix design method.

[0023] By adopting the above technical solution, a computer program is generated from the above low-carbon concrete mix design method and stored in a memory so that it can be loaded and executed by a processor. Thus, a smart terminal is made based on the memory and processor for convenient use.

[0024] Thirdly, the computer-readable storage medium provided in this application adopts the following technical solution: A computer-readable storage medium storing a computer program, which, when loaded and executed by a processor, employs the aforementioned low-carbon concrete mix design method.

[0025] By adopting the above technical solution, the above low-carbon concrete mix design method is generated into a computer program and stored in a computer-readable storage medium for loading and execution by a processor. The computer-readable storage medium facilitates the reading and storage of the computer program.

[0026] In summary, this application has at least one of the following beneficial technical effects: 1. First, estimate the initial carbon emissions of concrete, and adjust the concrete mix proportion according to the carbon emission standard to obtain the test mix proportion. Then, simulate the test mix proportion. The simulated test mix proportion is the final mix proportion, which makes it easier to control the carbon emissions of concrete within the carbon emission standard and effectively reduce the carbon emissions of concrete.

[0027] 2. If the initial carbon emissions do not meet the carbon emission standards, a new concrete mix proportion is first generated based on the concrete strength grade and the carbon emission standards. After the new concrete mix proportion meets the concrete engineering design standards, it is used as the test mix proportion. This ensures that the concrete meets both the concrete engineering design standards and the carbon emission standards, thereby effectively reducing the carbon emissions of the concrete while ensuring its quality.

[0028] 3. When the tested carbon emissions are less than the standard carbon emissions, the mix proportion of the concrete test materials is obtained according to the target mixing ratio, which effectively ensures the minimum carbon emissions of concrete and thus effectively reduces the carbon emissions of concrete.

[0037] The following is in conjunction with the appendix Figures 1 to 8 This application will be described in further detail.

[0038] This application discloses a method for designing the mix proportions of low-carbon concrete.

[0039] Reference Figure 1 A method for designing the mix proportions of low-carbon concrete includes the following steps: S101. Obtain the concrete type and the corresponding concrete materials and concrete mix proportions, and estimate the initial carbon emissions of the concrete based on the concrete materials and concrete mix proportions.

[0040] Concrete grades are used to distinguish different concrete materials and mix proportions. Common concrete grades include C15, C20, C25, and C30. Specifically, concrete grade C15 includes cement, sand, and gravel, with a mix proportion of cement:sand:gravel = 1:2:3 and a water-cement ratio of 0.6; concrete grade C20 includes cement, sand, and gravel, with a mix proportion of cement:sand:gravel = 1:1.5:3 and a water-cement ratio of 0.55; concrete grade C25 includes cement, sand, and gravel, with a mix proportion of cement:sand:gravel = 1:1:2 and a water-cement ratio of 0.5; and concrete grade C30 includes cement, sand, and gravel, with a mix proportion of cement:sand:gravel = 1:0.8:2 and a water-cement ratio of 0.45. In this embodiment, the concrete grade and its corresponding concrete materials and mix proportions are obtained from a preset carbon emission standard database.

[0041] It should be noted that the concrete mix proportions are affected by factors such as the construction environment and the intended use of the concrete, so the actual mix proportions may be adjusted.

[0042] Concrete materials include cementitious materials, aggregates, and additives used to enhance concrete performance. Cementitious materials refer to those used in concrete to bind the aggregates and allow them to harden, such as cement. Aggregates refer to mineral materials such as stones, gravel, and sand used in concrete to support and enhance its strength. Since cementitious materials and aggregates are the main sources of carbon emissions in concrete materials, the initial carbon emissions of concrete in this embodiment represent the carbon emissions of cementitious materials and aggregates in the concrete material.

[0043] Therefore, based on the concrete materials and mix design, the initial carbon emissions of concrete can be estimated from two aspects: cementitious materials and aggregates. Specifically, first, determine the amount of cement used in the concrete and calculate the required carbon emissions of cement based on the carbon emissions per unit of cement; second, determine the amount of aggregate used and calculate the carbon emissions of aggregate based on the carbon emissions per unit of aggregate; finally, add the carbon emissions of cement and the carbon emissions of aggregate to estimate the initial carbon emissions of concrete.

[0044] S102. Determine whether the initial carbon emissions meet the preset carbon emission standards based on the concrete type.

[0045] Different types of concrete have different carbon emission standards. Specifically, the carbon emission standard database stores different concrete types and their corresponding carbon emission standards. If the initial carbon emission level meets the standard, it means that the concrete's carbon emissions meet the standard, and the concrete can be designed with the current mix proportion. If the initial carbon emission level does not meet the standard, it means that the concrete's carbon emissions do not meet the standard, and the concrete mix proportion needs to be changed so that the designed concrete meets the carbon emission standard.

[0046] S103. If the initial carbon emissions do not meet the carbon emission standards, the concrete mix proportion shall be changed according to the carbon emission standards to obtain the test mix proportion.

[0047] If the initial carbon emissions do not meet the carbon emission standards, it indicates that the carbon emissions of the concrete do not meet the standards, and the concrete mix design needs to be changed. Specifically, the concrete mix design is modified according to the carbon emission standards to obtain a test mix design. The carbon emissions of the designed concrete can meet the carbon emission standards by reducing the proportion of cementitious materials or concrete aggregates.

[0048] S104. Simulate the test mix ratio.

[0049] The test mix design is uploaded to a preset simulation software to simulate the test mix design and determine whether the carbon emissions of the concrete designed based on the test mix design meet the carbon emission standards.

[0050] S105. Determine whether the test mix ratio passes the simulation based on the preset simulation conditions.

[0051] The simulation conditions are preset by humans. For example, the simulation conditions can be the proportion of cementitious materials, the proportion of aggregates, and the cost corresponding to the mix proportion. For example, if the simulation condition is the cost of concrete, it is first necessary to determine whether the cost of concrete meets the preset standard cost. If it does, the test mix proportion is deemed to have passed the simulation. That is, the concrete designed according to the concrete mix proportion meets the carbon emission standard, and the cost of this concrete also meets the preset standard cost. Therefore, the test mix proportion is deemed to have passed the simulation.

[0052] S106. If the simulation is successful, the test mix proportion shall be used as the final mix proportion.

[0053] If the test mix proportion passes the simulation, the test mix proportion will be used as the final mix proportion, and the concrete will be designed according to the final mix proportion.

[0054] It should be noted that a reference mix design can be set in the concrete mix design to optimize the algorithm. Furthermore, the concrete mix design process can be based on raw material parameters, apparent density, and raw material unit prices. Raw material parameters include water type, water influence coefficient, actual cement strength, mineral grade, mineral powder content, fly ash quality grade, fly ash content, silica fume replacement rate, silica fume content, fine aggregate type, fine aggregate specifications, fine aggregate influence coefficient, coarse aggregate type, coarse aggregate specifications, admixture content, and admixture water reduction rate. Apparent density refers to the actual density of the concrete surface. Raw material unit prices can be updated in real time via the internet, and reference parameters can also be set for raw materials to optimize the algorithm and save design time.

[0055] The implementation principle of this embodiment is as follows: First, the initial carbon emissions of concrete are estimated, and the mix proportion of concrete is adjusted according to the carbon emission standard to obtain the test mix proportion. Then, the test mix proportion is simulated, and the simulated test mix proportion is the final mix proportion. This makes it easier to control the carbon emissions of concrete within the carbon emission standard and effectively reduce the carbon emissions of concrete.

[0056] based on Figure 1 One implementation of the illustrated embodiment, through Figure 2 Please provide a detailed explanation.

[0057] Reference Figure 2 Estimating the initial carbon emissions of concrete based on its materials and mix design involves the following steps: S201. Obtain the carbon emissions per unit volume for each type of concrete material from the preset concrete material carbon emission statistics database.

[0058] The database of carbon emissions from concrete materials stores information on concrete materials and their corresponding carbon emissions per unit volume.

[0059] S202. Calculate the initial volume of each concrete material based on the preset total concrete volume and concrete mix proportion.

[0060] For example, if the total volume of concrete is 1200 cubic meters, and the concrete mix proportion is cement:sand:aggregate = 1:2:3, with a water-cement ratio of 0.6, then the initial volume of cement calculated based on the concrete mix proportion is... cubic meters, the initial volume of sand is cubic meters, the initial volume of the stones is cubic meter.

[0061] S203. Calculate the initial carbon emissions of the total concrete volume based on the initial volume of each concrete material and the carbon emissions per unit volume of each concrete material.

[0062] Taking step S202 as an example, if the initial volumes of cement, sand, and gravel in the concrete are calculated to be 200 cubic meters of cement, 400 cubic meters of sand, and 600 cubic meters of gravel, and the carbon emission per unit volume of cement is obtained from the concrete material carbon emission statistics database as 10 kg CO2e / cubic meter, the carbon emission per unit volume of sand is 5 kg CO2e / cubic meter, and the carbon emission per unit volume of gravel is 5 kg CO2e / cubic meter, then the initial carbon emission of the total concrete volume = 200*10 + 400*5 + 600*5 = 7000 kg CO2e.

[0063] The low-carbon concrete mix design method provided in this embodiment estimates the initial carbon emissions of concrete based on the initial volume of each concrete material, which helps to improve the accuracy of the initial carbon emissions calculation.

[0064] based on Figure 1 One implementation of the illustrated embodiment, through Figure 3 Please provide a detailed explanation.

[0065] Reference Figure 3 Determining whether the initial carbon emissions meet the preset carbon emission standards based on the concrete type involves the following steps: S301. Obtain the standard carbon emission corresponding to the concrete type from the preset carbon emission standard database.

[0066] The carbon emission standard database stores concrete types and their corresponding standard carbon emissions.

[0067] S302. Determine whether the initial carbon emissions are greater than the standard carbon emissions.

[0068] S303. If the value is greater than the standard, the initial carbon emissions are deemed not to meet the carbon emission standard.

[0069] S304. If it is not greater than, the initial carbon emissions are determined to meet the carbon emission standards.

[0070] If the initial carbon emissions are greater than the standard carbon emissions, it indicates that the initial carbon emissions will cause significant environmental pollution, and the initial carbon emissions are determined not to meet the carbon emission standards. If the initial carbon emissions are less than or equal to the standard carbon emissions, it indicates that the environmental pollution caused by the initial carbon emissions is within a controllable range, and the initial carbon emissions are determined to meet the carbon emission standards.

[0071] The low-carbon concrete mix design method provided in this embodiment compares the initial carbon emissions with the standard carbon emissions to determine whether the initial carbon emissions meet the carbon emission standards, thereby facilitating subsequent adjustments to the concrete mix proportions.

[0072] based on Figure 1 One implementation of the illustrated embodiment, through Figure 4 Please provide a detailed explanation.

[0073] Reference Figure 4 If the initial carbon emissions do not meet the carbon emission standards, the concrete mix proportions are modified according to the carbon emission standards to obtain the test mix proportions, including the following steps: S401. If the initial carbon emissions do not meet the carbon emission standards, obtain the concrete strength grade based on the concrete type.

[0074] If the initial carbon emissions do not meet the carbon emission standards, the concrete mix design needs to be adjusted to reduce carbon emissions. First, the concrete strength grade is obtained from the pre-set concrete management database based on the concrete type. Each concrete type has a different concrete strength grade, which refers to the maximum compressive or tensile force that concrete can withstand after a certain curing time on a standard specimen. For example, the concrete strength grade of type C25 concrete indicates that after 28 days of curing, the compressive strength is not less than 25 MPa.

[0075] S402. Generate a new concrete mix proportion based on the concrete strength grade and carbon emission standards.

[0076] The new concrete mix design must meet the standards for concrete strength grade and carbon emission. Specifically, since there are various concrete materials corresponding to different concrete strength grades, a new concrete mix design can be generated by replacing the original corresponding concrete materials with concrete materials that have lower carbon emissions while maintaining the same concrete strength grade.

[0077] S403. Determine whether the mix proportion of the new concrete meets the preset concrete engineering design standards.

[0078] S404. If satisfied, the new concrete mix proportion shall be used as the test mix proportion.

[0079] Concrete engineering design standards refer to the technical standards and specifications for concrete projects that are stipulated under the premise of ensuring the safety and reliability of concrete. These specifications and standards generally include all aspects of concrete design, construction, and curing, such as concrete composition, concrete mix proportions, and concrete construction techniques. In this embodiment, if the new concrete mix proportion is within the preset range of concrete mix proportions, it is determined that the new concrete mix proportion meets the concrete engineering design standards, and the new concrete mix proportion is used as the test mix proportion.

[0080] The low-carbon concrete mix design method provided in this embodiment first generates a new concrete mix proportion based on the concrete strength grade and the carbon emission standard if the initial carbon emission does not meet the carbon emission standard. After the new concrete mix proportion meets the concrete engineering design standard, the new concrete mix proportion is used as the test mix proportion. This allows the concrete to meet the carbon emission standard while meeting the concrete engineering design standard, thereby effectively reducing the carbon emission of the concrete and ensuring the quality of the concrete.

[0081] based on Figure 1 One implementation of the illustrated embodiment, through Figure 5 Please provide a detailed explanation.

[0082] Reference Figure 5 The process of generating a new concrete mix proportion based on concrete strength grade and carbon emission standards includes the following steps: S501, Selecting concrete test materials that meet the concrete strength grade; Concrete test materials include test cementitious materials.

[0083] Because different types of cementitious materials contain different chemical compositions and particle size distributions, they also differ in terms of reaction rate, reactivity, and hardening degree in concrete, which leads to different concrete strength grades. Therefore, concrete testing materials that match the concrete strength grade can be selected according to the concrete strength grade.

[0084] S502. Based on the statistical database of carbon emissions of concrete materials, obtain the target cementitious material with the largest carbon emissions per unit volume among all tested cementitious materials.

[0085] The concrete material carbon emission statistics database stores the tested cementitious materials and their corresponding carbon emissions per unit volume. Therefore, by searching the concrete material carbon emission statistics database, the target cementitious material with the highest carbon emissions per unit volume can be obtained.

[0086] S503. Obtain alternative test cementitious materials whose carbon emissions per unit volume are less than the preset threshold for carbon emissions per unit volume from the carbon emission statistics database of concrete materials.

[0087] The unit carbon emission threshold is preset by humans. If the unit carbon emission is less than the preset unit carbon emission threshold, it indicates that the unit carbon emission of the alternative cementitious material being tested is lower.

[0088] S504. Based on the proportion of the target test cementitious material in the concrete material, obtain the proportion of the alternative test cementitious material in the concrete material, and replace the target test cementitious material with the alternative test cementitious material to obtain a new concrete test material.

[0089] For example, if the proportion of the target cementitious material in the concrete is... The proportion of the alternative test cementitious material in the concrete material is: In the new concrete test material, the only difference between the target test cementitious material and the alternative test cementitious material is that the other concrete materials remain unchanged.

[0090] S505. Calculate the test carbon emissions of new concrete test materials based on the concrete material carbon emission statistics database.

[0091] Similar to steps S201 to S203, firstly, the unit volume test carbon emission of each new concrete test material is obtained from the concrete material carbon emission statistics database; secondly, the initial test volume of each new concrete test material is calculated based on the preset total concrete volume and concrete mix ratio; finally, the test carbon emission of the new concrete test material is calculated based on the initial test volume of each new concrete test material and the unit volume test carbon emission of each new concrete test material.

[0092] S506. If the tested carbon emissions are equal to the standard carbon emissions, the mix proportion of the new concrete test materials shall be used as the mix proportion of the new concrete.

[0093] If the tested carbon emissions are equal to the standard carbon emissions, it indicates that the mix proportion of the new concrete test material meets the carbon emission standard. Therefore, the mix proportion of the new concrete test material is taken as the mix proportion of the new concrete. If the tested carbon emissions are greater than the standard carbon emissions, it indicates that the mix proportion of the new concrete test material does not meet the carbon emission standard, and step S103 is then executed.

[0094] The low-carbon concrete mix design method provided in this embodiment selects suitable concrete testing materials according to the concrete strength grade, which facilitates the effective assurance of concrete material quality. When the tested carbon emissions are equal to the standard carbon emissions, the mix proportion of the new concrete testing materials is used as the new concrete mix proportion, which effectively reduces the carbon emissions of concrete while ensuring the quality of concrete.

[0095] based on Figure 1 One implementation of the illustrated embodiment, through Figure 6 Please provide a detailed explanation.

[0096] Reference Figure 6 The low-carbon concrete mix design method also includes the following steps: S601. If the tested carbon emissions are less than the standard carbon emissions, the substitute test cementitious material and the target test cementitious material will be mixed in different mixing ratios to form a mixed test cementitious material.

[0097] If the tested carbon emissions are less than the standard carbon emissions, it indicates that the tested carbon emissions meet the carbon emission standards. In this case, the substitute test cementitious material and the target test cementitious material will be mixed in different mixing ratios to form a mixed test cementitious material. It should be noted that the mixing ratio of the substitute test cementitious material and the target test cementitious material must be within a pre-set mixing ratio range.

[0098] S602. Calculate the mixed carbon emissions of the mixed test cementitious materials corresponding to each mixing ratio, and screen out the mixed carbon emissions that are greater than the preset cementitious material carbon emissions, and obtain the target mixed carbon emissions that are less than or equal to the cementitious material carbon emissions.

[0099] The steps for calculating the mixed carbon emissions of the mixed test cementitious material corresponding to each mixing ratio are as follows: First, obtain the unit volume mixed carbon emissions of the mixed test cementitious material from the concrete material carbon emission statistics database; second, the mixed carbon emissions of the mixed test cementitious material can be calculated based on the preset total concrete volume and unit volume mixed carbon emissions.

[0100] By filtering out mixed carbon emissions that exceed the preset carbon emissions of cementitious materials from all mixed carbon emissions, the carbon emissions of concrete are reduced.

[0101] S603. Obtain the minimum carbon emission among all target mixed carbon emissions, and take the mixing ratio of the alternative test cementitious material corresponding to the minimum carbon emission with the target test cementitious material as the target mixing ratio.

[0102] Since there are one or more target mixed carbon emissions, when there are multiple target mixed carbon emissions, the minimum carbon emission is obtained. In this case, the cementitious material corresponding to the minimum carbon emission is used as the alternative test cementitious material, and the mixing ratio of the alternative test cementitious material and the target test cementitious material is used as the target mixing ratio.

[0103] S604. Based on the target mixing ratio, obtain the mix proportion of the concrete test material and use the mix proportion of the concrete test material as the new concrete mix proportion.

[0104] For example, if the target mixing ratio is 1:2 for the substitute test cementitious material and 1:2 for the target test cementitious material, and the initial concrete mix ratio is 1:2:3, then the new concrete mix ratio will still be 1:2:3, but the ratio of the substitute test cementitious material will be... The target test cementitious material ratio is

[0105] The low-carbon concrete mix design method provided in this embodiment obtains the mix proportion of concrete test materials according to the target mixing ratio when the tested carbon emissions are less than the standard carbon emissions, effectively ensuring the minimum carbon emissions of concrete and thus effectively reducing the carbon emissions of concrete.

[0106] based on Figure 1 In one embodiment shown, the concrete material includes cementitious materials; the simulation conditions include the standard mix proportion of cementitious materials in the concrete material, referring to... Figure 7 The process of determining whether the test mix proportion passes the simulation based on preset simulation conditions includes the following steps: S701. Obtain the test proportion of cementitious materials in the test mix proportion.

[0107] For example, if the test mix ratio is: cement:sand:gravel = 1:2:3, then the test mix ratio for cementitious materials is:

[0108] S702. If the test mix ratio is less than or equal to the standard mix ratio, the test mix ratio is deemed to have passed the simulation.

[0109] The standard mix ratio is preset by humans. If the test mix ratio is less than or equal to the standard mix ratio, it indicates that the amount of cementitious material is too small. In this case, the test mix ratio is judged to pass the simulation. If the test mix ratio is greater than the standard mix ratio, the proportion of cementitious material is reduced so that the test mix ratio of cementitious material is less than or equal to the standard mix ratio.

[0110] The low-carbon concrete mix design method provided in this embodiment determines that the test mix proportion passes the simulation when it is less than the standard mix proportion. This effectively ensures the amount of cementitious materials in the concrete mix proportion, effectively reduces the amount of cementitious materials in the concrete, and thus effectively controls the cost of concrete.

[0111] based on Figure 1 In one embodiment of the shown example, the simulation conditions also include the standard cost of concrete materials, as referred to... Figure 8 The process of determining whether the test mix proportion passes the simulation based on preset simulation conditions also includes the following steps: S801. Obtain and test the concrete cost of the concrete materials corresponding to the mix proportion.

[0112] In this embodiment, the total volume of concrete is first obtained, and the volume of each concrete material is calculated based on the test mix proportion. Next, the unit volume selling price of each concrete material is obtained from a preset concrete price database. The concrete cost can then be calculated based on the unit volume selling price and the volume of each concrete material. Specifically, the unit volume selling price of each concrete material is multiplied by its corresponding volume to obtain the cost of each concrete material. Finally, the costs of all concrete materials are added together to obtain the total concrete cost.

[0113] S802. If the cost of concrete is less than or equal to the cost of standard concrete, the test mix proportion is deemed to have passed the simulation.

[0114] The standard concrete cost is preset by humans. If the concrete cost is less than or equal to the standard concrete cost, the test mix proportion is deemed to have passed the simulation. If the concrete cost is greater than the standard concrete cost, a lower-cost concrete material is used instead, but the concrete strength grade remains unchanged.

[0115] The low-carbon concrete mix design method provided in this embodiment determines that the test mix proportion passes simulation when the concrete cost is less than or equal to the standard concrete cost, thus effectively controlling the concrete cost.
