[0022] In the prior art, the traditional slump test is usually conducted after the concrete leaves the factory and before it is transported, and the workability of the concrete is inferred based on the slump test results. The traditional compressive strength test is usually conducted after the concrete leaves the factory and before it is transported. The compressive strength of the concrete is obtained by curing the sample in the laboratory.
[0023] However, during the transportation of concrete, its properties (such as consistency and fluidity) will change due to changes in mixing, drum speed, temperature of concrete during transportation, etc. When the concrete is transported to the construction site, the workability and compressive strength obtained before transportation are likely to be inaccurate. If the workability and compressive strength before transportation are used, it may have a serious impact on the quality and life of the building.
[0024] In the embodiment of the present invention, the initial parameters and transportation process parameters of the target concrete are obtained, and the initial parameters and transportation process parameters are input into the concrete quality assessment model to obtain the quality assessment result of the target concrete. Since the transportation process parameters of the target concrete during transportation are comprehensively considered, the quality assessment result of the concrete obtained is related to the parameter changes during the transportation of the concrete, that is, the influence of the parameter changes during the transportation process on the quality of the concrete is fully considered, so the quality assessment of the concrete transported to the construction site can be performed, and a more accurate quality assessment result can be obtained.
[0025] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0026] The embodiment of the present invention provides a method for obtaining concrete quality. Figure 1 , the following is a detailed description through specific steps.
[0027] Step 101 : acquiring initial parameters of target concrete and transportation process parameters associated with the quality of the target concrete during the process of transporting the target concrete by a transport vehicle.
[0028] In a specific implementation, the target concrete is the concrete that is transported to the construction site by a transport vehicle and used for construction. The transport vehicle may be a concrete mixer transport vehicle, also known as a mixer truck. The transport vehicle may include a cylindrical mixing drum (also known as a drum), and the concrete is loaded in the cylindrical mixing drum. The cylindrical mixing drum rotates during transportation to prevent the concrete from solidifying.
[0029] In an embodiment of the present invention, the initial parameters of the target concrete may include at least one of the following: the initial compressive strength of the target concrete, the initial workability of the target concrete, and the setting time of the target concrete. The transportation process parameters of the target concrete may include at least one of the following: the temperature of the target concrete, the air content in the target concrete, the transportation time of the target concrete, the mixing time of the target concrete in the drum of the transport vehicle, the drum motor power of the transport vehicle, and the slump of the target concrete.
[0030] In a specific implementation, after the target concrete leaves the factory and before it is transported, the initial compressive strength of the target concrete can be measured by the existing laboratory solidification sample method. The slump structure of the target concrete can be obtained through the existing slump test, and the initial workability of the target concrete can be inferred. The setting time of the target concrete can be obtained through the existing test method.
[0031] In practical applications, it can be known that the compressive strength of concrete can refer to the ability of concrete to withstand axial load (compression), which determines the structural capacity and durability of concrete.
[0032] The workability of concrete refers to the properties of concrete that are easy to construct and can achieve uniform quality and compact molding. The workability of concrete can include three aspects: fluidity, cohesion and water retention. These three aspects are interrelated and contradictory.
[0033] Fluidity refers to the property of concrete that it is easy to flow, transport and fill concrete formwork under the action of its own gravity or mechanical vibration.
[0034] Cohesion refers to the ability of concrete to maintain overall uniformity during the construction process. Good cohesion can ensure that the concrete does not delaminate or segregate during transportation, pouring, and molding, that is, it can ensure that the internal structure of the concrete is uniform after hardening.
[0035] Good water retention can ensure that there will be no large amount of water seepage during the transportation, molding and setting of concrete, which can avoid the large number of interconnected capillary pores caused by water seepage, and can also avoid the interface bonding defects caused by the accumulation of water in the coarse aggregate and the lower part of the steel bars due to water seepage. Water retention has a great influence on the strength and durability of concrete.
[0036] Setting time may refer to the time required for concrete to transition from a fluid state to a solid state.
[0037] In a specific implementation, the initial parameters of the target concrete usually do not change after being measured. That is, during the subsequent transportation process, the initial parameters of the target concrete can be regarded as fixed.
[0038] In a specific implementation, the initial parameters of the target concrete may further include the material type of the target concrete. The material type of the target concrete may refer to a specific mix ratio formula of the target concrete, and the specific mix ratio formula may be used for a specific purpose or specific performance requirements.
[0039] In the embodiment of the present invention, unlike the initial parameters of the target concrete, the transportation process parameters of the target concrete are dynamically changed.
[0040] In a specific implementation, the temperature of the target concrete (ie, the internal temperature of the target concrete) may include a temperature change curve of the target concrete during transportation, representing the real-time temperature of the target concrete at different time points during transportation. The above different time points may be represented at preset time intervals.
[0041] For example, the preset time interval is 1 minute. During the transportation of the target concrete, the real-time temperature of the target concrete is acquired every one minute, thereby obtaining a temperature variation curve of the target concrete during the entire transportation process.
[0042] The air in the target concrete usually exists in the form of tiny bubbles. The air content in the target concrete is the amount of air mixed in the target concrete.
[0043] In specific applications, it is known that the air content in concrete has an impact on the workability and compressive strength of the target concrete. The air content in concrete can be controlled by adding air-entraining agents to the concrete. Air-entraining agents can be used to improve the durability of concrete, especially in environments affected by freeze-thaw cycles.
[0044] By increasing the air content in concrete, small bubbles can be evenly distributed in the concrete, making the concrete more fluid. In addition, the plasticity and cohesion of the concrete are improved, and segregation (separation of aggregate from cement paste) is reduced. When the air content in concrete is high, the friction between particles can be reduced, making the concrete easier to prevent and spread, and the concrete is more workable. In addition, the workability of the concrete can also be improved.
[0045] When the air content in concrete increases, the compressive strength of concrete decreases because small bubbles occupy the space originally filled by aggregate / cement. In some special application scenarios, such as in an environment with freeze-thaw cycles, increasing the air content in concrete can improve the durability of concrete.
[0046] In a specific implementation, the transportation time in the transportation process parameters is the time taken for the target concrete to be loaded and transported to the construction site.
[0047] In a specific implementation, the mixing time in the transport process parameter is the duration of the target concrete being mixed in the drum of the transport vehicle. In some embodiments, the mixing time may also include the duration of the target concrete being mixed in the factory.
[0048] In a specific implementation, the drum motor power of the transport vehicle in the transport process parameter refers to the power of the drum motor of the transport vehicle to keep the concrete stirring during the transport process. Based on the drum motor power, the slump of the target concrete can be calculated.
[0049] For concrete with lower slump (higher hardness), its resistance is greater and the output power of the drum motor is higher; for concrete with higher slump (lower hardness), its resistance is smaller and the output power of the drum motor is lower. Therefore, by measuring the power of the drum motor, the slump of the target concrete can be calculated.
[0050] In some embodiments, the slump of the target concrete can also be measured by a slump sensor disposed in the drum. The slump sensor obtains the slump of the target concrete by detecting the resistance encountered by the target concrete during the rotation of the drum.
[0051] For concrete with a lower slump (harder), the slump sensor experiences greater resistance; while for concrete with a higher slump, the slump sensor experiences less resistance.
[0052] In the embodiment of the present invention, the slump of the target concrete may change with the change of the transportation time. Therefore, the slump of the target concrete during the transportation process may include the slump of the target concrete at different time points during the transportation process.
[0053] In some embodiments, the slump of the target concrete in different time periods may be acquired at preset time intervals to obtain the slump change of the target concrete during transportation.
[0054] For example, the preset time interval is 10 minutes, and the slump value measured by the slump sensor is obtained every 10 minutes, so as to obtain the slump change of the target concrete during the whole transportation process.
[0055] That is to say, in the embodiment of the present invention, the transportation process parameters of the target concrete may include continuous values of the parameters of the target concrete at different times during the transportation process, which may reflect the continuous change trend of the parameters of the target concrete during the transportation process.
[0056] In a specific implementation, the transportation process parameters may further include at least one of the following: the ambient temperature during the pouring of the target concrete, the air humidity during the pouring of the target concrete, and the total weight and volume of the target concrete in the transport vehicle.
[0057] Step 102: input the initial parameters and the transportation process parameters into a preset concrete quality assessment model to obtain a quality assessment result of the target concrete.
[0058] In an embodiment of the present invention, after obtaining the initial parameters and the transportation process parameters of the target concrete, the initial parameters and the transportation process parameters of the target concrete may be input into a preset concrete quality assessment model to obtain a quality assessment result of the target concrete.
[0059] In a specific implementation, the quality assessment result of the target concrete may include: the workability assessment result of the target concrete and the compressive strength assessment result of the target concrete. The workability assessment result of the target concrete may include the real-time workability assessment result of the target concrete and the estimated workability assessment result in the future (such as transportation to the construction site).
[0060] In the embodiment of the present invention, the concrete quality assessment model can be trained by the following steps:
[0061] Step 1), establish the initial evaluation model.
[0062] Specifically, you can choose a suitable neural network architecture, such as a convolutional neural network (CNN), a recurrent neural network (RNN), or a Transform model.
[0063] Step 2), simulating the process of transporting sample concrete in a laboratory scenario to obtain simulated transportation parameters.
[0064] In an embodiment of the present invention, a sample concrete can be prepared in a laboratory scenario using a laboratory mixer. The production conditions such as material proportions and environmental parameters for preparing the sample concrete can be the same as those for preparing the target concrete. Thus, it can be ensured that the properties of the sample concrete are the same or substantially the same as those of the target concrete.
[0065] The transportation process parameters of the target concrete during transportation are simulated as the simulated transportation parameters. The simulated transportation parameters may include at least one of the following: the temperature of the sample concrete, the air content in the sample concrete, the slump of the sample concrete, the mixing time of the sample concrete, the slump of the sample concrete, and the power of the mixer for mixing the sample concrete.
[0066] The mixer power of the sample concrete is used to characterize the drum motor power during the transportation of the target concrete.
[0067] Thus, the transport process parameters of the target concrete transport process are simulated based on the sample transport parameters of the sample concrete.
[0068] Step 3), test the workability and compressive strength of the concrete sample.
[0069] In a specific implementation, after the simulated transportation of the sample concrete, a portion is selected from it as a sample to measure the workability and compressive strength of the sample concrete. In this scenario, the workability and compressive strength of the sample concrete after the simulated transportation can be obtained.
[0070] In some embodiments, the slump of the sample concrete after simulated transportation can be obtained through a slump test method, and then the workability of the sample concrete after simulated transportation can be obtained based on the slump.
[0071] Specifically, after simulated transportation, the sample concrete can be poured into the slump bucket. After each filling, use a tamping hammer to evenly hit the wall of the bucket several times, tamping it and smoothing it, and then pull up the slump bucket. The sample concrete collapses due to its own weight. The height of the highest point of the sample concrete after collapse is subtracted from the height of the bucket to get the slump of the sample concrete. The higher the slump, the better the usability of the concrete.
[0072] The slump bucket is in the shape of a trumpet. In some scenarios, the upper opening of the slump bucket is 100 millimeters (mm), the lower opening is 200 mm, and the height is 300 mm.
[0073] In a specific implementation, a selected portion of the sample concrete after simulated transportation can be cast to obtain a test object. The test object is usually in the shape of a cylinder or a cube. After that, the test object is cured for a standard time (such as 7 days, 28 days), and then the compressive strength of the test object is measured using a compression testing machine.
[0074] Based on the above compressive strength measurement, the real compressive strength data of different curing times can be obtained.
[0075] That is to say, in the above step 3), the actual quality result of the sample concrete after simulated transportation can be obtained. The above actual quality result is the real workability and real compressive strength corresponding to the sample concrete.
[0076] Step 4), taking the simulated transport parameters as the input of the initial evaluation model, taking the workability and compressive strength of the sample concrete as the output of the initial evaluation model, training the initial evaluation model, and obtaining the concrete quality evaluation model.
[0077] In the specific implementation, since the simulated transportation parameters of the sample concrete, as well as the slump and compressive strength of the sample concrete after simulated transportation can be obtained in advance, the obtained concrete quality assessment model can characterize the mapping relationship between input (transportation process parameters) and output (slump and compressive strength).
[0078] In a specific implementation, a dynamic parameter weighting algorithm may be used to train the initial evaluation model.
[0079] The dynamic parameter weighted algorithm is based on real-time performance feedback. By dynamically adjusting the weights of various input parameters (i.e., simulated transportation parameters), a more accurate concrete quality assessment model can be obtained.
[0080] The above-mentioned dynamic parameter weighting algorithm takes into account that different input parameters (such as temperature, air content, mixing time, etc.) have different effects on concrete quality (workability, compressive strength, etc.) under different circumstances. Therefore, it is necessary to adjust the importance of different input parameters according to different scenarios, and then dynamically adjust the model training.
[0081] Specifically, initial weights may be assigned to the input parameters first. For example, corresponding initial weights may be assigned to different input parameters based on theoretical values or historical importance.
[0082] During the production process of sample concrete and after the production is completed, the quality indicators (workability, compressive strength) of the sample concrete are obtained in real time, and the quality indicators of the sample concrete are used as the output of the concrete quality evaluation model.
[0083] After the concrete quality assessment model is obtained, the concrete quality assessment model is calibrated based on the quality assessment result and the workability and compressive strength of the sample concrete obtained in the above step 3).
[0084] Specifically, the actual error between the quality assessment result and the actual quality result may be obtained, and the actual error may include mean square error (MSE), mean absolute error (MAE), etc., or include obtaining a loss function of a quality assessment model, etc. Based on the actual error, the weight of each input parameter is adjusted accordingly.
[0085] If an input parameter (such as the temperature of the sample concrete) is closely related to the actual error, that is, the change of the input parameter has a greater impact on the actual error, the weight of the input parameter can be increased; if the correlation between an input parameter and the actual error is poor, that is, the change of the input parameter has a smaller impact on the actual error, the weight of the input parameter can be reduced. Based on the input parameters after weight adjustment, the concrete quality assessment model is calibrated, and after multiple cycles, the final concrete quality assessment model is obtained.
[0086] In specific implementations, reinforcement learning methods, Bayesian optimization methods, neural networks with attention mechanisms, etc. can be used to achieve dynamic parameter weighting.
[0087] It is understandable that the specific method of establishing a concrete quality assessment model is not limited to the above-mentioned dynamic parameter weighting algorithm, and other model training methods can also be used to obtain a concrete quality assessment model.
[0088] In the embodiment of the present invention, the trained quality assessment model may also be corrected based on relevant data of the target concrete acquired at the construction site.
[0089] In a specific implementation, the actual workability and actual compressive strength of the target concrete can be obtained at the construction site. Further, based on the actual workability and actual compressive strength, the quality assessment model is corrected. Since the actual workability and actual compressive strength can better represent the actual scene, the quality assessment model is calibrated by the actual workability and actual compressive strength, which can improve the prediction accuracy of the assessment results of the quality assessment model.
[0090] Specifically, the actual slump of the target concrete can be obtained at the construction site through a slump bucket, thereby obtaining the actual workability of the target concrete. A portion of the target concrete is selected and cast into a test object, and after the test object is cured for a standard time (such as 7 days or 28 days), the compressive strength of the test object is measured using a compression testing machine.
[0091] The principle of the specific process of obtaining the actual workability and actual compressive strength of the above-mentioned target concrete can adopt existing solutions and will not be elaborated here.
[0092] In the embodiment of the present invention, when the quality assessment model is revised, the field data of the construction site can also be obtained. Then, based on the field data of the construction site, the actual workability and the actual compressive strength, the quality assessment model is revised.
[0093] In a specific implementation, the field data may include at least one of the following: temperature changes at the construction site, ambient humidity at the construction site, actual transportation time of the target concrete, etc. Based on the field data, the impact of some parameter changes at the construction site on the quality of the target concrete can be captured. Thus, the prediction accuracy of the evaluation results of the quality evaluation model can be further improved.
[0094] In specific implementation, the quality assessment model can be continuously fed back and corrected by obtaining the initial parameters, transportation process parameters, etc. of a large number of different batches of target concrete, so as to obtain a more accurate quality assessment model.
[0095] Reference Figure 2 , a schematic diagram of the relationship between workability and transportation time of a target concrete in an embodiment of the present invention is given. The estimated workability of the target concrete is obtained by using the concrete quality acquisition method provided in an embodiment of the present invention.

The dotted line 202 is the estimated workability obtained by the concrete quality acquisition method provided by the embodiment of the present invention. It can be seen that as the transportation time increases, the workability of the target concrete gradually decreases.

[0099] In summary, the initial parameters and transportation process parameters of the target concrete are obtained, and the initial parameters and transportation process parameters are input into the concrete quality assessment model to obtain the quality assessment result of the target concrete. Since the transportation process parameters of the target concrete during transportation are comprehensively considered, the quality assessment result of the concrete obtained is related to the parameter changes during the transportation of the concrete, that is, the influence of the parameter changes during the transportation process on the quality of the concrete is fully considered, so the quality assessment of the concrete transported to the construction site can be carried out, and a more accurate quality assessment result can be obtained.
[0100] In the embodiment of the present invention, after the quality assessment result of the target concrete is obtained, the quality assessment result can be fed back to the staff at the construction site. When the quality assessment result indicates that the quality of the target concrete is abnormal, the target concrete can be adjusted in time, such as by adding water, raising the temperature, etc., to ensure that the quality of the target concrete meets the quality standard.
