Description

Technical Field

[0001] This invention discloses a test and analysis method and apparatus for the road performance of steel slag and mineral powder composite admixture concrete, which belongs to the field of construction quality closed-loop technology. Background Technology

[0002] Currently, the road performance testing of steel slag and mineral powder composite admixture concrete mainly relies on manual operation of test data, manual recording of data, and subjective judgment results. This results in problems such as lack of compliance verification for test data parameter entry, lack of time control for key operation nodes in specimen preparation and curing processes, poor data comparability due to inconsistent conditions between different batches of test data, and strong subjectivity due to the isolation of multi-source performance test data and reliance on experience for comprehensive rating. Summary of the Invention

[0003] The purpose of this application is to provide a method and apparatus for testing and analyzing the road performance of steel slag and mineral powder composite admixture concrete, so as to at least solve the technical problem of non-compliant verification of parameter input caused by manual operation in the test data of steel slag and mineral powder composite admixture concrete for road performance in the prior art.

[0004] According to one aspect of the present invention, in order to achieve the above-mentioned objective, a method for testing and analyzing the road performance of steel slag and mineral powder composite admixture concrete is provided, comprising the following steps: Based on the basic information of the entered test data and the mixing ratio parameters, compliance verification is performed to obtain a standardized raw dataset; Based on the standardized raw dataset, the key operation nodes of the specimen preparation and curing process of steel slag and mineral powder composite admixture concrete were controlled in sequence to obtain test data specimens that meet the curing age. Based on the test data, the specimens were subjected to sequential working performance tests, mechanical performance tests, durability tests, and volume stability tests. The collected test data were then weighted and comprehensively rated to obtain the road performance suitability level and the optimal blending range.

[0005] Furthermore, compliance verification is performed based on the entered experimental data and mix proportion parameters to obtain a standardized raw dataset, including: Verify whether the total composite content of steel slag and mineral powder in the mix proportion parameters exceeds the upper limit for road concrete mix proportions; Verify whether the dimensional deviations of the molded specimens are within the allowable range specified in the standard. Verify whether the environmental parameters of the test data and the maintenance environment parameters meet the standards; Verify whether there are missing data or abnormal extreme values ​​in the basic information and mix proportion parameters of the test data; If any verification fails, the program will issue an alert and terminate the subsequent test data flow.

[0006] Furthermore, when the total composite content of steel slag and mineral powder in the mix proportion parameters exceeds the upper limit for road concrete mix proportions, a program warning is triggered and the subsequent test data flow is terminated, including: The output includes a warning message containing the exceeded value and the identifier of the exceeded item; Lock the interface for generating standardized raw datasets and prohibit it from entering the specimen preparation stage; Archive the early warning information, the basic information of the currently entered test data, and the mixing ratio parameters.

[0007] Furthermore, based on the standardized raw dataset, the key operational nodes of the specimen preparation and curing process of steel slag and mineral powder composite admixture concrete were time-controlled to obtain test data specimens that met the curing age requirements, including: According to the road concrete forming process, the system outputs prompts for mixing time, mixing speed, vibration time, finishing and settling time, and time to enter the curing room in a preset sequence. It monitors the curing time, curing temperature and curing humidity in real time, and automatically outputs a prompt message to retrieve the test data specimen before the test data specimen reaches the predetermined curing age; Record and archive the time nodes of all preparation operations and the information on the curing process.

[0008] Furthermore, based on the test data, the specimens undergo performance testing and mechanical property testing, including: Collect slump, spread, bleeding state, mixing uniformity, and segregation state information of the steel slag and mineral powder composite admixture concrete mixture. The collected measured values ​​and status information are compared with the standards for the workability of highway pavement construction to classify the workability grade of the mixture. Mechanical failure tests were conducted on the specimens after curing at early age, standard age, and long age, and the failure load and ultimate stress value were collected at each age. Data corresponding to test specimens with abnormal damage were screened out, and the remaining valid data were compared with the corresponding strength values ​​of the baseline blank concrete specimens.

[0009] Furthermore, based on the test data, durability performance test data and volume stability test data of the specimens are performed, including: For the test specimens, conduct freeze-thaw cycle test data, water penetration test data, and drying shrinkage deformation test data, and record the number of freeze-thaw cycles, water penetration depth value, and drying shrinkage deformation value; Monitor the volumetric deformation and shrinkage / expansion states of the specimens during the early and long-term curing stages, and collect expansion change values. According to the road concrete durability performance specification standard, determine whether the test data specimens meet the specification limit requirements for frost resistance, impermeability, drying shrinkage and volume stability.

[0010] Furthermore, the volume stability test data also include: When the expansion change value exceeds the preset stability threshold, the mix proportion corresponding to the test data specimen is determined to be unqualified for road use, and the subsequent rating process for the mix proportion is terminated. When cracking or warping occurs in the volume deformation state, the defect type is marked and the steel slag content ratio in the mix proportion parameters is correlated for cause analysis.

[0011] Furthermore, the collected test data are weighted and comprehensively rated to obtain the road performance suitability level and optimal blending range, including: The weighted calculation is performed according to the preset weight allocation scheme, which is as follows: the weight of mechanical bearing performance index is the first weight value, the weight of long-term durability performance index is the second weight value, the weight of construction performance index is the third weight value, and the weight of volume stability index is the fourth weight value. Among them, the first weight value is greater than the second weight value, and the second weight value is greater than the third and fourth weight values. Based on the weighted calculation results, three applicable levels are output: excellent fit level, qualified fit level and unqualified fit level. Based on the weighted calculation results, the optimal dosage range of steel slag and mineral powder in the mix proportion parameters is output, along with the applicable road types and key points for construction control corresponding to the optimal dosage range.

[0012] According to one embodiment of the present invention, a test and analysis device for the road performance of steel slag and mineral powder composite admixture concrete is also provided, comprising: The verification module is used to perform compliance verification based on the basic information of the entered test data and the mixing ratio parameters to obtain a standardized raw dataset; The control module is used to perform time-series control on key operation nodes of the specimen preparation and curing process of steel slag and mineral powder composite admixture concrete based on standardized raw datasets, so as to obtain test data specimens that meet the curing age. The rating module is used to perform sequential performance tests, mechanical property tests, durability tests, and volume stability tests on the test specimens based on the test data, and to perform a weighted comprehensive rating on the collected test data to obtain the road performance suitability level and the optimal blending range.

[0013] According to another aspect of the present invention, a computer-readable storage medium is also provided, the computer-readable storage medium including a stored executable program, wherein, when the executable program is running, it controls the device where the computer-readable storage medium is located to execute the test and analysis method for road performance of steel slag and mineral powder composite admixture concrete according to various embodiments of the present invention.

[0023] Example 1 Figure 1 This is a flowchart of a test analysis method for the road performance of steel slag and mineral powder composite admixture concrete according to one embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps: Step S110: Based on the entered basic information of the experimental data and the mix proportion parameters, perform compliance verification to obtain a standardized raw dataset. The specific steps are as follows: In step S110, after the basic information of the test data and the mix proportion parameters are received, the process automatically enters the compliance verification process. The basic information of the test data includes the test data item number, test data ambient temperature, test data ambient humidity, description of curing conditions, cement base raw material parameters, steel slag admixture grade, mineral powder admixture grade, coarse aggregate specifications, fine aggregate specifications, admixture type, concrete design mix proportion, steel slag admixture ratio of a single specimen, mineral powder admixture ratio, total amount of composite admixture, specimen molding specifications, curing age classification, and corresponding highway pavement grade requirements. The mix proportion parameters include the respective mass percentages of steel slag and mineral powder, the water-cement ratio, and aggregate gradation data.

[0024] The compliance verification process checks each input item according to the built-in mandatory control standards for road concrete, employing a pre-interception logic: if any verification item fails, an alert is triggered and the subsequent process is terminated until the corrected data is reloaded before restarting. Specific verification rules are as follows: Verify whether the total composite content of steel slag and mineral powder in the mix proportion parameters exceeds the upper limit for road concrete admixtures; verify whether the specimen molding size deviation is within the allowable range of the specifications; verify whether the environmental parameters of the test data and curing environment meet the standards; verify whether there are any missing data or abnormal extreme values ​​in the basic information of the test data and mix proportion parameters.

[0025] When a verification anomaly is detected, a warning message containing the out-of-limit value and the out-of-limit item identifier is automatically output and displayed as a pop-up window. Simultaneously, the interface for generating the standardized raw dataset is locked, preventing further progress to the specimen preparation stage. Once all verification items pass, the entered raw information is standardized, invalid and garbled data is removed, and a standardized raw dataset that is well-organized, compliant, and directly usable for experimental analysis is generated. This dataset is then encrypted and stored synchronously. At this point, compliance verification is complete, and the standardized raw dataset is obtained.

[0026] Step S120: Based on the standardized raw dataset, the key operational nodes of the specimen preparation and curing process of steel slag and mineral powder composite admixture concrete are controlled sequentially to obtain test data specimens that meet the curing age. The specific steps are as follows: In step S120, during the specimen preparation stage, the timing control process outputs various operation prompts sequentially according to a preset timing sequence. Specifically, based on the mix proportion parameters and specimen molding specifications in the standardized raw dataset, a mixing time prompt is automatically calculated and output, matching the uniformity requirements of the steel slag powder composite admixture. Subsequently, a stirring speed prompt is output to ensure that the stirring process conforms to the predetermined speed range. After stirring is completed, a vibration time prompt is output, which is related to the specimen size and the compaction characteristics of the composite admixture. After vibration is completed, a surface finishing and settling time prompt is output, followed by a curing chamber entry time prompt after settling. The output order of the above timing nodes is fixed; once the operation time corresponding to the previous node reaches a preset threshold, the prompt output state of the next node is automatically entered.

[0027] During the curing phase, the time-series control process receives real-time data on curing duration, temperature, and humidity from the curing environment monitoring equipment. The real-time monitored values ​​are compared with preset curing parameter thresholds in the standardized raw dataset. If a monitored value exceeds the allowable deviation range, an environmental anomaly warning is automatically issued. Simultaneously, the curing duration is continuously recorded, and a prompt to retrieve the specimen is automatically issued before it reaches the predetermined curing age. The predetermined curing age includes early age, standard age, and long age, each corresponding to different performance test data requirements.

[0028] The actual execution time of each key operation node in the specimen preparation process, environmental fluctuation data during curing, and the time point of reaching the predetermined curing age are all recorded and archived to form a complete operation log. The above-mentioned timing control process requires no manual intervention and automatically switches nodes and records data according to preset logic. When all curing nodes are completed and the specimen reaches the predetermined curing age, the timing control process is completed, and test data specimens that meet the curing age are obtained.

[0029] Step S140 involves sequentially performing workability test data, mechanical property test data, durability test data, and volume stability test data on the test specimen based on the test data. The collected test data are then weighted and comprehensively rated to obtain the road performance suitability level and optimal blending range. The specific steps are as follows: In step S140, after obtaining test data specimens that meet the curing age, the test data specimens are subjected to workability test data, mechanical property test data, durability test data and volume stability test data in sequence.

[0030] Workability test data is used to evaluate the construction compatibility of steel slag and mineral powder composite admixture concrete mixtures. Slump, spread, bleeding status, mixing uniformity, and segregation status information of the mixture are collected. The collected measured values ​​and status information are compared with the workability specifications for highway pavement construction, and the workability level of the mixture is automatically classified as excellent, acceptable, or unacceptable. When bleeding, segregation, or insufficient fluidity are observed in the mixture, the defect type is automatically marked, and the cause is analyzed in conjunction with the steel slag and mineral powder proportions in the mix proportion parameters.

[0031] Mechanical performance test data are used to evaluate the load-bearing capacity of steel slag and mineral powder composite admixture concrete. Mechanical failure tests are conducted on cured specimens at early age, standard age, and long age, collecting failure load values ​​and ultimate stress values ​​at each age. Based on the collected failure load values, the measured compressive strength, flexural strength, and splitting tensile strength of each set of test data specimens are automatically calculated. Data corresponding to abnormally damaged test data specimens are automatically filtered out, and the remaining valid data are compared with the corresponding strength values ​​of baseline blank concrete specimens to determine whether the load-bearing capacity requirements of the corresponding grade of highway pavement are met.

[0032] Durability test data are used to evaluate the long-term service performance of steel slag and mineral powder composite admixture concrete. Freeze-thaw cycle tests, water penetration tests, and drying shrinkage tests are conducted on the test specimens, recording the number of freeze-thaw cycles, water penetration depth, and drying shrinkage. According to the road concrete durability performance specification, it is determined whether the freeze-thaw resistance, water penetration resistance, and drying shrinkage performance of the test specimens meet the specified limits.

[0033] Volumetric stability test data is used to investigate the expansion risk caused by the hydration of free calcium oxide and magnesium oxide in steel slag. The volumetric deformation and shrinkage / expansion states of the test specimens are monitored during the early and long-term curing stages, and expansion change values ​​are collected. According to the road concrete durability performance specification, it is determined whether the volumetric stability meets the specification limits. When the expansion change value exceeds the preset stability threshold, the mix proportion corresponding to the test specimen is deemed unqualified for road use, and the subsequent rating process for the mix proportion is terminated. When cracking or warping occurs in the volumetric deformation state, the defect type is marked and the causal analysis is performed in conjunction with the steel slag content ratio in the mix proportion parameters.

[0034] After completing all the performance test data, a weighted comprehensive rating was performed on the collected test data. The weighted calculation was conducted according to a preset weighting scheme: mechanical bearing capacity was the first weight value, long-term durability was the second weight value, construction performance was the third weight value, and volumetric stability was the fourth weight value. The first weight value was greater than the second weight value, and the second weight value was greater than both the third and fourth weight values. Based on the weighted calculation results, three applicability levels were output: excellent fit, acceptable fit, and unacceptable fit. The optimal mixing ratio range for steel slag and mineral powder in the mix proportion parameters was also output, along with the applicable road types and construction control points corresponding to the optimal mixing ratio range. Thus, the road performance applicability level and optimal mixing range were obtained.

[0035] Based on steps S110 to S140 above, in this embodiment of the invention, by verifying the basic information and mix proportion parameters of the test data for compliance, the accuracy and completeness of the original data are ensured; by controlling the timing of key operation nodes in the specimen preparation and curing process, the standardization and consistency of the specimen conditions are guaranteed; by sequentially executing multiple performance test data and performing weighted comprehensive rating on the collected test data, the automated determination of road performance and the objective output of the optimal blending range are realized, improving the standardization and evaluation accuracy of the test data results, thereby solving the technical problem of non-compliant verification of parameter input caused by manual operation in the test data of steel slag and mineral powder composite admixture concrete for road performance in the prior art.

[0036] The test and analysis method for the road performance of steel slag and mineral powder composite admixture concrete in embodiments of the present invention further includes: performing compliance verification based on the input test data basic information and mix proportion parameters to obtain a standardized raw dataset, including: verifying whether the total composite admixture of steel slag and mineral powder in the mix proportion parameters exceeds the upper limit of road concrete admixture; verifying whether the specimen molding size deviation is within the allowable range of the specification; verifying whether the test data environmental parameters and curing environmental parameters meet the standards; verifying whether there are missing data or abnormal extreme values ​​in the test data basic information and mix proportion parameters; when any verification fails, a program warning is triggered and the subsequent test data process is terminated, effectively avoiding the implementation of invalid test data and ensuring the compliance and reliability of the test data.

[0037] Furthermore, when the total composite content of steel slag and mineral powder in the mix proportion parameters exceeds the upper limit of road concrete mix proportion, the program triggers an early warning and terminates the subsequent test data flow, including: outputting an early warning message containing the exceeding value and the exceeding item identifier; locking the generation interface of the standardized original dataset to prevent it from entering the specimen preparation stage; and archiving the early warning message, the currently entered test data basic information, and the mix proportion parameters. This achieves immediate blocking of mix proportion exceeding the limit and full traceability, fundamentally preventing unqualified mix proportions from entering the specimen preparation stage.

[0038] Furthermore, based on standardized raw datasets, key operational nodes in the preparation and curing processes of steel slag and mineral powder composite admixture concrete were subjected to time-series control to obtain test data specimens that met the curing age requirements. This included: outputting prompts for mixing time, mixing speed, vibration time, surface finishing and settling time, and time to enter the curing chamber according to a preset time sequence, following the road concrete forming process; real-time monitoring of curing time, curing temperature, and curing humidity, and automatically outputting prompts to retrieve test data specimens before they reached the predetermined curing age; and recording and archiving all preparation operation time node information and curing process information, thus achieving standardized time-series control of the entire process from mixing to curing, effectively ensuring the consistency and traceability of test data specimen conditions.

[0039] Furthermore, based on the test specimens, workability and mechanical performance test data were performed, including: collecting slump, spread, bleeding state, mixing uniformity, and segregation state information of the steel slag and mineral powder composite admixture concrete mixture; comparing the collected measured values ​​and state information with the highway pavement construction workability specifications to classify the workability level of the mixture; conducting mechanical destructive tests on the cured test specimens at early age, standard age, and long age, collecting the destructive load and ultimate stress value at each age; filtering out the data corresponding to test specimens with abnormal damage, and comparing the remaining valid data with the corresponding strength values ​​of the benchmark blank concrete specimens, thus achieving a comprehensive, accurate, and standardized evaluation of the construction adaptability and load-bearing capacity of the steel slag and mineral powder composite admixture concrete.

[0040] Furthermore, based on the test data specimens, durability performance test data and volumetric stability test data were performed, including: conducting freeze-thaw cycle test data, water penetration test data, and drying shrinkage deformation test data on the test data specimens, recording the number of freeze-thaw cycles, water penetration depth value, and drying shrinkage deformation value; monitoring the volumetric deformation state and shrinkage expansion state of the test data specimens during the early curing stage and long-term curing stage, and collecting expansion change values; and determining whether the freeze-thaw resistance, impermeability, drying shrinkage performance, and volumetric stability of the test data specimens meet the specification limits according to the road concrete durability performance standard, thus achieving a comprehensive assessment and hazard screening of the long-term service performance and volumetric stability of the material.

[0041] Furthermore, the volume stability test data also includes: when the expansion change value exceeds the preset stability threshold, the mix proportion corresponding to the test data specimen is determined to be unqualified for road use, and the subsequent rating process of the mix proportion is terminated; when cracking or warping occurs in the volume deformation state, the defect type is marked and the steel slag content ratio in the mix proportion parameters is correlated for cause analysis, realizing the immediate rejection of volume expansion risk and accurate tracing of defect causes.

[0042] Furthermore, the collected test data are weighted and comprehensively rated to obtain the applicable road performance level and optimal blending range. This includes: weighted calculation according to a preset weighting scheme, where the mechanical bearing capacity index is the first weight value, the long-term durability index is the second weight value, the construction performance index is the third weight value, and the volume stability index is the fourth weight value, where the first weight value is greater than the second weight value, and the second weight value is greater than both the third and fourth weight values; based on the weighted calculation results, three applicable levels are output: excellent compatibility level, qualified compatibility level, and unqualified level; based on the weighted calculation results, the optimal blending range of steel slag and mineral powder in the mix proportion parameters, as well as the applicable road types and construction control points corresponding to the optimal blending range, are output, realizing the scientific quantitative rating and precise optimization of the road performance of steel slag and mineral powder composite admixture concrete.
