Description

Technical Field

[0001] The invention belongs to the technical field of concrete admixture preparation sampling and relates to a concrete admixture preparation sampling detection and analysis system. Background Art

[0002] Concrete admixtures are substances added during the mixing process to improve the performance of concrete. The quality of concrete admixtures has a crucial impact on the performance of concrete. Sampling and testing can ensure that each batch of admixtures produced meets the established standards in terms of composition and performance. At the same time, we can gain an in-depth understanding of the changes in admixtures during the production process. Testing samples at different reaction stages and analyzing the evolution of their chemical composition and properties will help optimize reaction conditions and improve product performance. Therefore, research based on sampling, testing and analysis of concrete admixture preparation is of great significance.

[0003] In the prior art, there are also related schemes for preparing and sampling concrete admixtures for testing. For example, a Chinese invention patent application with publication number CN117606981A is for a method for evaluating the water reduction rate of an admixture for UHPC, which comprises: first preparing a reference mortar to obtain a reference mortar, then determining the water consumption of the reference mortar to obtain the water consumption M0 for the fluidity of the reference mortar, then preparing a test mortar to obtain a test mortar, and finally determining the water consumption of the test mortar, the water consumption Ms for the fluidity of the test mortar, and obtaining the water reduction rate by a mortar water reduction rate calculation method. The invention uses a mass ratio of reference cement to the sand of 1:2, so that the prepared test mortar is closer to the composition of UHPC, thereby improving the accuracy of the test results. The stirring procedure is more conducive to the release of the water-reducing effect of the admixture, and the water content in the admixture is subtracted when calculating the water reduction rate, so that the water reduction rate calculation is more accurate.

[0004] In addition, a Chinese invention patent application for a rapid determination method of the optimal calcination temperature of concrete admixtures prepared from coal gangue with publication number CN106908476A includes: using a thermogravimetric analyzer to measure the TG-DSC curve of coal gangue in an oxygen atmosphere and an argon atmosphere respectively, and determining the optimal calcination temperature range of high-activity concrete admixtures produced from coal gangue through the DSC curves of coal gangue under different atmospheres. This method can determine the optimal calcination temperature of coal gangue within a few hours. Compared with conventional methods such as the 28-day curing strength comparison of cement mortar and the calcium absorption determination method, the method of the present invention has the dual advantages of being fast and accurate. In addition, this method can also determine the carbonaceous content in coal gangue through the weight loss difference under oxygen atmosphere and argon atmosphere, providing an important reference index for the uniform mixing of coal gangue raw materials.

[0005] Although the above two schemes have proposed some solutions for sampling and testing of concrete admixture preparation, there are still certain limitations: on the one hand, some existing technical schemes for concrete admixture quality testing usually focus on the analysis of the quality testing process, ignoring the targeted monitoring of the sampling process of the sampling device. This analysis method cannot accurately reflect the true situation of the product. When faced with admixtures with stratification, the problem of a single sampling position is prone to occur, resulting in a lack of representativeness of the sample. These deficiencies will distort the test data, and the quality judgment made based on this will be inaccurate, which may allow unqualified products to enter the market, bury hidden dangers in the quality of concrete projects, and affect the safety and durability of the project.

[0006] On the other hand, some existing technical solutions lack the analysis of sampling intervals based on reaction progress when monitoring the admixture preparation process, thus failing to achieve dynamic sampling. This analysis method cannot sample based on key reaction nodes. In the preparation of polymerization-type admixtures, it is easy to miss the quality inspection opportunities at different reaction stages, making it difficult to accurately control product quality, resulting in unstable finished product quality. Moreover, without reasonable sampling based on reaction progress, it is impossible to provide key data for production process improvement, which hinders the optimization of production processes, is not conducive to improving production efficiency and product performance, and is difficult to meet the growing engineering quality requirements. Summary of the invention

[0007] In view of this, in order to solve the problems raised in the above background technology, a concrete admixture preparation sampling detection and analysis system is now proposed.

[0008] The object of the present invention can be achieved through the following technical scheme: A concrete admixture preparation sampling detection and analysis system, including: a sampling device setting module, used to set a mobile sampling device, the mobile sampling device includes a grabbing component, a transverse telescopic component and a longitudinal telescopic component, and a plurality of sampling ports are arranged on the longitudinal telescopic component.

[0009] The sampling position analysis module is used to use a three-dimensional scanning device to obtain three-dimensional data of the target reaction device, obtain the sampling center point of the target reaction device and the monitoring sampling distance threshold, analyze the lateral adaptation of the mobile sampling device in the initial state, determine whether the mobile sampling device needs to be adjusted laterally, and perform the adjustment operation if necessary.

[0010] The sampling operation implementation module is used to use a mobile sampling device to sample the target concrete admixture reaction process to obtain samples corresponding to each longitudinal telescopic component.

[0011] The sample data acquisition module is used to monitor the reaction progress of each sample corresponding to each longitudinal telescopic component, and obtain the reaction progress evaluation data of each sample corresponding to each longitudinal telescopic component, specifically including chemical composition evaluation data and physical parameter evaluation data.

[0012] The sample data analysis module is used to analyze the target concrete admixture reaction process completion evaluation status based on the reaction process evaluation data of each sample corresponding to each longitudinal telescopic component, and determine whether to allow the reaction operation to be terminated. If allowed, the reaction operation is terminated; if not allowed, the next sampling time is further identified.

[0013] The data repository is used to store the reference density, reference viscosity and reference proportion of each active ingredient corresponding to the target concrete admixture.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention provides a mobile sampling device, which includes a plurality of longitudinal telescopic components, and a plurality of sampling ports are provided on the longitudinal telescopic components. The mobile sampling device can realize the sampling of concrete admixtures at different reaction depths in different reaction areas, greatly improving the representativeness of the samples, overcoming the limitation that traditional sampling is only carried out at a specific position or shallow layer, and can comprehensively cover all levels and areas of the reaction, so that the collected samples can more truly reflect the overall admixture quality. Moreover, this comprehensive sampling can more accurately monitor the admixture reaction process, provide a more accurate basis for quality control, help optimize the production process, effectively ensure the product quality of concrete admixtures, and improve production efficiency.

[0015] (2) The present invention determines whether it is necessary to perform lateral adjustment of the mobile sampling device by analyzing the lateral adaptation of the initial state of the mobile sampling device. This analysis method can significantly improve the sampling accuracy. Different admixture reaction environments are different. After analysis and adjustment, the sampling port can be accurately aligned with the key reaction area to obtain more representative samples and ensure the reliability of the test results. At the same time, the adaptability of the equipment is greatly enhanced, and it can flexibly respond to reaction vessels of different types and sizes and process adjustments without the need for customized equipment, thereby reducing costs. In addition, it can also ensure production continuity, avoid resampling due to improper sampling position, reduce production interruptions, improve production efficiency, and effectively promote the quality control and efficient operation of concrete admixture production.

[0016] (3) The present invention analyzes the completion evaluation of the target concrete admixture reaction process and then determines whether to allow the reaction operation to be terminated. This analysis method can ensure that the product quality meets the standard and avoid quality defects caused by insufficient or excessive reaction. At the same time, this method helps to improve production efficiency, accurately determine the reaction endpoint, and terminate the reaction in time, preventing unnecessary time waste and reducing energy consumption. In addition, it can effectively reduce production costs, avoid defective products caused by improper reaction control, improve the utilization rate of raw materials, and bring good economic benefits and quality assurance to the production of concrete admixtures.

[0017] (4) The present invention further identifies the next sampling time when judging that the reaction operation is not allowed to be terminated. This analysis method can make the monitoring of the production process more scientific and accurate. By determining a reasonable next sampling time, the key changes in the reaction process can be captured in time without missing any details that affect the quality of the admixture, which helps to optimize the production process and avoid frequent or unnecessary sampling operations, saving manpower and time costs and improving production efficiency. Samples obtained based on the accurate next sampling time can provide more reliable data support for subsequent reaction control, help accurately control the reaction process, and ensure the final production of high-quality concrete admixtures.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1As shown, the present invention provides a sampling, detection and analysis system for preparing concrete admixtures, including a sampling device setting module, a sampling device adjustment module, a sampling operation implementation module, a sample data acquisition module, a sample data analysis module and a data storage library, wherein the sampling device setting module is connected to the sampling device adjustment module, the sampling device adjustment module is connected to the sampling operation implementation module, the sampling operation implementation module is connected to the sample data acquisition module, the sample data acquisition module is connected to the sample data analysis module, and the data storage library is connected to the sample data analysis module.

[0026] The sampling device setting module is used to set up the mobile sampling device. Figure 2 , Figure 3 As shown, the mobile sampling device includes a grabbing component, a transverse telescopic component and a longitudinal telescopic component, and a plurality of sampling ports are arranged on the longitudinal telescopic component.

[0027] It should be noted that the longitudinal telescopic component includes a plurality of longitudinal sampling sections, the length of each sampling section can be changed, and the sampling port is located at the center point of each sampling section.

[0028] It should be noted that the length of the transverse telescopic component can be changed.

[0029] It should be noted that, when performing the sampling operation, a mechanical gripper or other gripping device may be used to grip the gripping component of the mobile sampling device, thereby controlling the movement of the mobile sampling device in the vertical and horizontal directions.

[0030] It should be noted that the present invention provides a mobile sampling device, which includes a plurality of longitudinal telescopic parts, and a plurality of sampling ports are provided on the longitudinal telescopic parts. The mobile sampling device can realize the sampling of concrete admixtures at different reaction depths in different reaction areas, greatly improving the representativeness of the samples, overcoming the limitation that traditional sampling is only carried out at a specific position or shallow layer, and can comprehensively cover all levels and areas of the reaction, so that the collected samples can more truly reflect the overall admixture quality. Moreover, this comprehensive sampling can more accurately monitor the admixture reaction process, provide a more accurate basis for quality control, help optimize the production process, effectively ensure the product quality of concrete admixtures, and improve production efficiency.

[0031] The sampling device adjustment module is used to obtain the three-dimensional data of the target reaction device using a three-dimensional scanning device. Figure 4 As shown, the sampling center point of the target reaction device and the monitoring sampling distance threshold are obtained, the lateral adaptation of the mobile sampling device in the initial state is analyzed, and it is determined whether the mobile sampling device needs to be adjusted lateraly. If necessary, the adjustment operation is performed.

[0032] It should be noted that the sampling center point refers to the position above the center line of the target reaction device determined based on a preset reference sampling height.

[0033] It needs to be explained that the monitoring sampling distance threshold refers to the structural radius of the target reaction device.

[0034] In a preferred embodiment of the present invention, the analysis of the lateral adaptation of the initial state of the mobile sampling device requires the construction of a lateral adaptation index of the initial state of the mobile sampling device, and the specific analysis method is as follows: extracting the monitoring sampling distance threshold of the target reaction device, and obtaining the initial lateral monitoring distance corresponding to the initial state of the lateral telescopic component of the mobile sampling device.

[0035] It should be explained that the initial state of the transverse telescopic component refers to the placement state of the mobile sampling device when no sampling operation is performed.

[0036] Half of the monitoring sampling distance threshold of the target reaction device is used as the reference sampling distance of the target reaction device.

[0037] It is necessary to explain why half of the threshold of the monitoring sampling distance of the target reaction device is used as the reference sampling distance of the target reaction device: this position is often the center point of the directional area, which has an advantage that cannot be ignored. In the reaction device, with the center point as the benchmark, the diffusion of substances and the reaction process are relatively balanced in all directions. When the solution is stirred and reacted, the sample at this point can integrate the reaction information of different radial positions, comprehensively present the overall reaction situation, and avoid the one-sidedness of the sample caused by edge or local sampling. From an operational perspective, determining the reference sampling distance with the center point greatly simplifies the sampling planning. Operators do not need to locate it in a complex device with difficulty, thereby improving the sampling efficiency and accuracy, reducing the errors caused by positioning difficulties, and ensuring the comparability between samples. From the perspective of reaction kinetics, the center point is the key site for the interaction between reactants, where factors such as reactant concentration and reaction rate are balanced. Sampling at this position can accurately capture the core characteristics of the reaction, provide a key basis for analyzing the reaction process and judging the reaction stage, and help to accurately control the reaction and ensure stable product quality.

[0038] The initial lateral monitoring distance of the mobile sampling device is calculated by difference with the reference sampling distance of the target reaction device, and then the absolute value is taken to obtain the initial lateral monitoring distance deviation value of the mobile sampling device, and then the ratio is calculated with the reference sampling distance of the target reaction device, and then the inverse is taken to obtain the initial state lateral adaptation index of the mobile sampling device.

[0039] In a preferred embodiment of the present invention, the specific method for determining whether lateral adjustment of the mobile sampling device is required is as follows: extracting the lateral adaptation index of the initial state of the mobile sampling device, and then comparing it with a preset reference initial state lateral adaptation index; if the lateral adaptation index of the initial state of the mobile sampling device is greater than or equal to the reference initial state lateral adaptation index, it is determined that lateral adjustment of the mobile sampling device is not required; otherwise, it is determined that lateral adjustment of the mobile sampling device is required.

[0040] Exemplarily, the lateral adaptation index of the reference initial state is 10.

[0041] It should be explained that the reference initial state lateral adaptation index is set based on the following: First, the size of the reaction device is an important consideration. Reaction devices of different sizes have different internal reaction area distributions, and the lateral positions of the adapted sampling devices are also different. For example, for large reaction devices, the sampling device needs to cover a larger range, and the lateral adaptation index must be set based on this. Secondly, the internal structural characteristics of the reaction device cannot be ignored, such as the presence or absence of obstacles, stirring methods, etc. These will affect the flow and distribution of admixtures in the device, and thus affect the rationality of the sampling position, and need to be fully considered when setting the index. Furthermore, the distribution of the target sampling area is crucial. Only by clarifying the location of the key reaction area can the set index help the mobile sampling device to accurately align, obtain the most representative samples, and ensure the accuracy of subsequent testing and analysis.

[0042] It should be noted that the present invention analyzes the lateral adaptation of the initial state of the mobile sampling device, and then determines whether it is necessary to perform lateral adjustment of the mobile sampling device. This analysis method can significantly improve the sampling accuracy. There are differences in the reaction environments of different admixtures. After analysis and adjustment, the sampling port can be accurately aligned with the key reaction area to obtain more representative samples and ensure reliable test results. At the same time, the adaptability of the equipment is greatly enhanced, and reaction vessels and process adjustments of different types and sizes can be flexibly responded to without custom equipment, reducing costs. In addition, it can also ensure production continuity, avoid resampling due to improper sampling position, reduce production interruptions, improve production efficiency, and effectively promote the quality control and efficient operation of concrete admixture production.

[0043] In a preferred embodiment of the present invention, the specific method of performing the adjustment operation is as follows: extracting the reference sampling distance of the target reaction device and the initial lateral monitoring distance of the mobile sampling device, and comparing the reference sampling distance of the target reaction device and the initial lateral monitoring distance of the mobile sampling device.

[0044] If the reference sampling distance of the target reaction device is greater than the initial lateral monitoring distance of the mobile sampling device, the difference between the reference sampling distance of the target reaction device and the initial lateral monitoring distance of the mobile sampling device is calculated to obtain the reference adjustment length, and the specific adjustment operation is determined to be elongation, and then each lateral telescopic component is adjusted.

[0045] If the reference sampling distance of the target reaction device is smaller than the initial lateral monitoring distance of the mobile sampling device, the difference between the initial lateral monitoring distance of the mobile sampling device and the reference sampling distance of the target reaction device is calculated to obtain the reference adjustment length, and the specific adjustment operation is determined to be shortening, and then each lateral telescopic component is adjusted.

[0046] It should be noted that when adjusting each transverse telescopic component, the adjustment operation of each transverse telescopic component remains consistent.

[0047] It should be noted that the present invention only analyzes the adjustment requirements of the transverse telescopic components, but does not analyze the adjustment requirements of the longitudinal telescopic components. The reasons are as follows: 1. Under normal circumstances, the longitudinal height of the reaction device is relatively large, which makes the longitudinal reaction conditions significantly different. In order to ensure that representative samples at different depths can be collected, the longitudinal telescopic components generally need to be adjusted, and this adjustment requirement is almost a given. For example, in a tall tower reaction device, the temperature, concentration and other parameters change significantly from top to bottom. In order to fully reflect the reaction situation, the longitudinal telescopic components must be adjusted to sample at different heights. In this case, the significance of analyzing the adjustment requirements of the longitudinal telescopic components is relatively small. 2. The situation in the transverse direction is more complex and changeable. Different reaction devices have huge differences in their internal transverse structures and reaction states. Some reaction devices have obstacles inside, or the stirring method causes uneven distribution of transverse materials, and these factors will affect the accuracy of sampling. In addition, the transverse telescopic components do not need to be adjusted in all cases, so it is necessary to analyze their adjustment requirements to determine whether they need to be adjusted and how to adjust them, so that the mobile sampling device can accurately obtain representative samples in the transverse position.

[0048] The sampling operation implementation module is used to use a mobile sampling device to sample the target concrete admixture reaction process to obtain samples corresponding to each longitudinal telescopic component.

[0049] It should be noted that different transverse telescopic components (longitudinal telescopic components) correspond to samples in different directional areas, different sampling nodes correspond to samples at different depths, and the same transverse telescopic node corresponds to one longitudinal telescopic node.

[0050] The sample data acquisition module is used to monitor the reaction progress of each sample corresponding to each longitudinal telescopic component, and obtain reaction progress evaluation data of each sample corresponding to each longitudinal telescopic component, specifically including chemical composition evaluation data and physical parameter evaluation data.

[0051] In a preferred embodiment of the present invention, the chemical composition evaluation data includes the proportion of each effective ingredient.

[0052] It should be explained that the reason for choosing the proportion of each effective ingredient as the chemical composition evaluation data is: on the one hand, it can directly reflect the essential characteristics of the product. The performance of concrete admixtures depends on the proportion of each effective ingredient. For example, the water reduction and slump retention performance will be different if the proportion of polycarboxylic acid-based water-reducing agent is different. On the other hand, it is convenient for quality control and standardized production. Enterprises can monitor production according to the set proportion range, make timely adjustments when deviations are found, and ensure stable product quality. In addition, the proportion of effective ingredients is closely related to product performance and application effects, and can be used to predict application performance, providing a basis for R&D personnel to optimize formulas and meet different engineering needs.

[0053] Exemplarily, the concrete admixture may be a water reducing agent, an early strength agent, a retarder and an air entraining agent.

[0054] For example, taking polycarboxylic acid-based water reducer as an example, the corresponding active ingredients may be polycarboxylic acid macromolecular chains and polyether side chains.

[0055] It should be supplemented that the proportion of each active ingredient can be obtained using a high performance liquid chromatograph.

[0056] In a preferred embodiment of the present invention, the physical parameter evaluation data includes monitoring density and monitoring viscosity.

[0057] It should be explained that the reasons for choosing density monitoring and viscosity monitoring as physical parameter evaluation data are: First, density monitoring and viscosity monitoring are closely related to product quality. Density can reflect the composition and concentration of admixtures. Deviating from the standard may lead to quality problems; viscosity affects its dispersion and effect in concrete. Second, density monitoring and viscosity monitoring have an indicative effect on application performance. Density affects the distribution of admixtures in concrete mixtures, and viscosity is related to concrete construction performance, such as pumping resistance. Third, density monitoring and viscosity monitoring are easy to monitor and the data is reliable. There are many mature methods for measuring density and viscosity. The equipment is easy to operate and can quickly obtain accurate data, providing a strong basis for quality control and performance optimization.

[0058] It should be noted that the monitored density and monitored viscosity can be obtained using a densitometer and a rotational viscometer, respectively.

[0059] The sample data analysis module is used to analyze the target concrete admixture reaction process completion evaluation status based on the reaction process evaluation data of each sample corresponding to each longitudinal telescopic component, and determine whether to allow the reaction operation to be terminated. If allowed, the reaction operation is terminated; if not allowed, the next sampling time is further identified.

[0060] In a preferred embodiment of the present invention, the target concrete admixture reaction process completion evaluation situation needs to construct a target concrete admixture reaction process completion evaluation index, and the specific method is as follows: extract the proportion of each effective component corresponding to each sample of each longitudinal telescopic component, and record them as ,in Indicates the number of the longitudinal telescopic component. , Indicates the number of longitudinal expansion components. Indicates the sample number, , represents the number of samples, Indicates the number of the active ingredient. , Indicates the number of effective ingredients, and analyzes the chemical composition compliance evaluation index corresponding to the reaction process of the target concrete admixture .

[0061] Extract the monitoring density and monitoring viscosity corresponding to each sample of each longitudinal telescopic component and record them as , , the physical parameter compliance evaluation index corresponding to the reaction process of the target concrete admixture is obtained by analysis .

[0062] Using the formula The target concrete admixture reaction process completion evaluation index is obtained by analysis. ,in They represent the weight factors corresponding to the preset chemical composition compliance evaluation index and physical parameter compliance evaluation index, respectively. .

[0063] For example, .

[0064] It should be noted that the weight factors corresponding to the chemical composition compliance evaluation index and the physical parameter compliance evaluation index are set based on the following: The weight factors corresponding to the chemical composition compliance evaluation index and the physical parameter compliance evaluation index are set based on many factors. From the perspective of chemical composition, it directly determines the core performance of the admixture. For example, the proportion of components such as polycarboxylic acid macromolecular chains in water reducers greatly affects the water reduction and collapse protection effects, and has a profound impact on the quality of concrete, so the relevant weights should be higher. From the perspective of physical parameters, density and viscosity affect the dispersion and construction performance of admixtures in concrete. For example, viscosity affects the difficulty of pumping, but compared with chemical composition, its effect on the change of the essential properties of concrete is slightly weaker, and the weight setting will be slightly lower. At the same time, different construction scenarios and engineering requirements will also adjust the weights. For example, for projects with high durability requirements, more emphasis will be placed on the weight of chemical composition.

[0065] In a preferred embodiment of the present invention, the specific method of analyzing and obtaining the chemical composition compliance evaluation index corresponding to the reaction process of the target concrete admixture is as follows: extracting the proportion of each effective component corresponding to each sample of each longitudinal telescopic component , and then use the formula The chemical composition compliance evaluation index corresponding to the reaction process of the target concrete admixture is obtained by analysis ,in Indicates taking the minimum value, Indicates the reference proportion of each effective share.

[0066] It should be noted that the present invention, by analyzing the target concrete admixture reaction process completion evaluation situation, then judges whether to allow the reaction operation to be terminated, this analysis method can ensure that the product quality is up to standard, and avoids quality defects caused by insufficient or excessive reaction. At the same time, this method helps to improve production efficiency, accurately judge the reaction endpoint, and can terminate the reaction in time, prevent unnecessary time waste, and reduce energy consumption. In addition, it can also effectively reduce production costs, avoid defective products caused by improper reaction control, improve raw material utilization, and bring good economic benefits and quality assurance for concrete admixture production.

[0067] In a preferred embodiment of the present invention, the specific method of analyzing and obtaining the physical parameter compliance evaluation index corresponding to the reaction process of the target concrete admixture is as follows: extracting the monitoring density corresponding to each sample of each longitudinal telescopic component and monitoring viscosity , using the formula The physical parameter compliance evaluation index corresponding to the reaction process of the target concrete admixture is obtained by analysis ,in Indicates the reference density of the target concrete admixture, Indicates the reference viscosity of the target concrete admixture.

[0068] In a preferred embodiment of the present invention, the specific analysis method for determining whether to allow the reaction operation to be terminated is as follows: extracting the reaction process completion evaluation index of the target concrete admixture, and then comparing it with a preset reaction process completion evaluation index threshold; if the reaction process completion evaluation index of the target concrete admixture is greater than or equal to the reaction process completion evaluation index threshold, it is determined that the reaction operation is allowed to be terminated; otherwise, it is determined that the reaction operation is not allowed to be terminated.

[0069] Exemplarily, the threshold value of the reaction process completion evaluation index is 0.95.

[0070] It should be noted that the basis for setting the threshold of the reaction process completion evaluation index is crucial. It is mainly based on the principle of chemical reaction kinetics, and determines the degree of progress required for the reaction to achieve the desired effect by studying the reaction rate, changes in reactant concentration, etc. At the same time, the performance standards of admixtures will be referenced to ensure that the product performance meets the standards. In addition, it is necessary to combine production process and cost considerations to ensure production efficiency while avoiding excessive reaction and increasing costs, and scientifically set the threshold by integrating multiple factors.

[0071] In a preferred embodiment of the present invention, the specific method of identifying the next sampling time is as follows: extracting the target concrete admixture reaction process completion evaluation index, and then multiplying it with the preset reference sampling interval to obtain the next sampling interval time correction amount, performing a difference calculation between the reference sampling interval and the next sampling interval time correction amount to obtain the next sampling interval time, and then obtaining the next sampling time based on the time of the current sampling operation.

[0072] Exemplarily, the reference sampling interval is .

[0073] What needs to be explained is the reason for identifying the next sampling time: during the reaction process of concrete admixtures, the reaction rate and degree of change are different at different stages. As the reaction proceeds, the reaction may enter a critical stage. For example, when preparing polycarboxylic acid-based water reducers by polymerization, the late reaction may be an important period for polymer chain growth and functionalization. At this stage, key parameters such as the proportion of effective ingredients and molecular weight of the product may change rapidly. Increasing the detection frequency can capture these key changes more accurately and ensure that the reaction proceeds in the expected direction. If the detection frequency is too low, parameter changes at critical stages may be missed, resulting in the final product not meeting the requirements.

[0074] It should be noted that the present invention further identifies the next sampling time when judging that the reaction operation is not allowed to be terminated. This analysis method can make the monitoring of the production process more scientific and accurate. By determining a reasonable next sampling time, the key changes in the reaction process can be captured in time, and any details that affect the quality of the admixture will not be missed. It is helpful to optimize the production process and avoid frequent or unnecessary sampling operations, which not only saves manpower and time costs, but also improves production efficiency. Samples obtained based on the accurate next sampling time can provide more reliable data support for subsequent reaction control, help accurately control the reaction process, and ensure the final production of high-quality concrete admixtures.

[0075] The data repository is used to store the reference density, reference viscosity and reference proportion of each active ingredient corresponding to the target concrete admixture.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they shall all fall within the protection scope of the present invention.
