In actual construction, mortar needs to take into account multiple performance indicators such as operability, fluidity, water retention and bonding strength. These indicators influence and restrict each other: good fluidity is conducive to paving and leveling, but if the water retention performance is insufficient, hollowing and cracking are prone to occur in the later hardening; insufficient bonding strength will cause the risk of falling off when subjected to force or environmental changes.

[0003] In order to improve the performance of mortar, it is necessary to test various indicators of mortar, and then improve the mortar formula based on the test results. However, the existing testing technology has the problems of scattered equipment, difficulty in comprehensively evaluating multiple indicators under unified conditions, many testing experiments and long testing cycles.

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.

[0070] A surface plate 3, the surface plate 3 is installed on the upper surface of the platform to simulate the material of the substrate surface;

[0071] A thickness detection device 4, wherein the thickness detection device 4 is disposed on the side of the surface plate 3, and the detection surface of the thickness detection device 4 is parallel to the working surface of the surface plate 3, and is used to detect the thickness of the mortar coating;

[0072] The pushing device is installed on the side of the surface plate 3. The pushing direction of the pushing device is parallel to the surface plate 3, and is used to push out the hardened mortar to evaluate the bonding strength of the mortar.

It can realize the anti-slip performance evaluation, thickness detection, and bonding strength test of the mortar coating in the same device, thereby improving the detection efficiency and reducing the improvement cycle of the mortar formula. The angle adjustment device 23 can be used to study the sliding behavior of the mortar under different tilt conditions, so that the test process is more in line with the actual construction environment. By setting the thickness detection device 4, the mortar coating thickness of each experiment can be maintained at the same thickness, thereby reducing the variables of the experiment and making the mortar performance detection more accurate.

[0075] like Figure 2 As shown, in some embodiments, the mounting platform 2 includes a first mounting sub-platform 21 and a second mounting sub-platform 22, the first mounting sub-platform 21 is mounted on the horizontal seat 1 through the angle adjustment device 23, the second mounting sub-platform 22 is mounted on the horizontal seat 1 through the weight detection device 24, and the platform surfaces of the first mounting sub-platform 21 and the second mounting sub-platform 22 are flush;

[0076] The surface plate 3 includes a first plate 31 and a second plate 32, and the first plate 31 and the second plate 32 are respectively arranged on the first mounting sub-platform 21 and the second mounting sub-platform 22;

[0077] The pushing device is installed on the side of the second plate 32 ; the adhesion detection device is installed on the back side of the first mounting sub-platform 21 away from the surface plate 3 .

[0078] Generally speaking, after the mortar slip test, the mortar will separate from the surface plate 3, while the water retention test requires the mortar to remain on the surface plate 3. In this case, two experiments are required to test the anti-slip performance and water retention performance of the mortar.

[0079] The embodiment of the present application sets up a double platform, so that after applying the mortar once, the flow / slip test of the mortar can be carried out while detecting the weight change of the mortar during the hardening process, which reduces the number of experiments and improves the experimental efficiency.

[0080] Figure 3 It is a flow chart of a method for detecting mortar construction performance according to some embodiments of the present invention.

[0081] like Figure 3 As shown, the embodiment of the present application further provides a method for detecting mortar construction performance, which is based on a mortar construction performance detection system as described in any one of the above items, and includes:

[0082] S1. Prepare mortar according to the preset proportion and stir evenly;

[0083] S2. Adjust the mounting platform to a horizontal state through the angle adjustment device and apply mortar on the surface plate;

[0084] S3. measuring the initial thickness and initial weight of the mortar;

[0085] S4, adjusting the slope of the mounting platform at a preset slope angle for multiple times, observing and recording the flow distance-time curve of the mortar at each current slope angle, and the critical slope angle at which the mortar starts to slip;

[0086] S5. After the mortar hardens, measure the hardened weight and contact area of ​​the mortar;

[0087] S6. Pushing the hardened mortar by a pushing device, wherein the pushing is performed in a direction parallel to the surface plate to obtain a thrust required to push the hardened mortar;

[0088] S7. Based on the initial weight, hardened weight, flow distance-time curve, current slope angle, critical slope angle, contact area and thrust, a weight-based comprehensive evaluation is performed to obtain the comprehensive performance of the mortar.

[0089] The present application provides a method for detecting the construction performance of mortar, which covers the main links of mortar performance evaluation from the preparation of mortar to the testing process, including initial thickness, initial weight, flow distance-time curve, critical slope angle, hardening weight, contact area and push test force, etc. The data is comprehensive, systematic, and the test efficiency is high, which can effectively reduce the improvement cycle of mortar formula; by adjusting the slope angle in sections and observing and recording the flow behavior, the flow characteristics and anti-slip ability of the mortar under different inclined conditions can be more clearly grasped; finally, based on the weighted comprehensive evaluation model, the comprehensive performance of the mortar under construction is more accurately reflected, which is conducive to the optimization of the formula and the improvement of the construction process.

[0090] In some embodiments, the step of adjusting the slope of the mounting platform at a preset slope angle for multiple times is performed based on the first mounting sub-platform;

[0091] The measuring of the initial thickness, initial weight, hardened weight and contact area of ​​the mortar and the jacking are performed based on the second mounting sub-platform.

[0092] When the mounting platform includes a first mounting sub-platform and a second mounting sub-platform, the method for detecting the mortar construction performance includes the following steps:

[0093] Prepare mortar according to the preset proportion and mix well;

[0094] The first mounting sub-platform and the second mounting sub-platform are adjusted to a horizontal state by using an angle adjustment device, and mortar is evenly applied on the surface plates of the first mounting sub-platform and the second mounting sub-platform;

[0095] Based on the weight detection device on the second mounting sub-platform, measure the initial weight of the mortar;

[0096] Based on the thickness detection device, the initial thickness of the mortar is measured;

[0097] The inclination angle of the first mounting sub-platform is adjusted at a preset slope angle for multiple times, and the flow distance-time curve of the mortar at each current slope angle and the critical slope angle at which the mortar starts to slide are observed and recorded;

[0098] After the coating of the mortar on the second mounting sub-platform is completely hardened, the weight detection device is used again to measure the hardened weight and contact area of ​​the mortar, and the contact area of ​​the hardened mortar;

[0099] The hardened mortar is pushed by a pushing device installed on the side of the second mounting sub-platform, and the pushing is carried out in a direction parallel to the surface plate to obtain the thrust required to push the hardened mortar.

[0100] Based on the initial weight, hardened weight, flow distance-time curve, current slope angle, critical slope angle, contact area and thrust, a weight-based comprehensive evaluation is performed to obtain the comprehensive performance of the mortar.

[0101] By conducting different experiments on two sub-platforms, the measurement of the initial thickness, initial weight, hardened weight and contact area of ​​the mortar, as well as the pushing operation, are concentrated on the second mounting sub-platform. The operation process is clearer and the test resources are effectively allocated, which can improve the experimental efficiency and reduce the experimental time. At the same time, the environment of the two sub-platforms can be maintained the same, thereby improving the accuracy of the experiment.

[0102] In some embodiments, the weight-based comprehensive evaluation is performed based on the initial weight, hardened weight, flow distance-time curve, current slope angle, critical slope angle, contact area and thrust to obtain the comprehensive performance of the mortar, including:

[0103] Based on the current slope angle and the flow distance-time curve, a fluidity index of the mortar is obtained;

[0104] Based on the initial weight and the hardened weight, obtaining the water retention rate of the mortar;

[0105] Based on the contact area and the thrust, the bonding strength of the mortar is obtained;

[0106] Based on the fluidity index, the water retention rate, the critical slope angle and the bonding strength, a comprehensive evaluation based on weights is performed to obtain the comprehensive performance of the mortar.

[0107] In some embodiments, obtaining the fluidity index of the mortar based on the current slope angle and the flow distance-time curve includes:

[0108] Based on the flow distance-time curve, the average flow rate at each current slope angle is calculated by a trapezoidal integration algorithm;

[0109] Based on the average flow rate at each current slope angle, the fluidity of the mortar is evaluated by a weighting algorithm to obtain a fluidity index of the mortar.

[0110] By performing trapezoidal integration on the flow distance-time curve at each current slope angle, the average flow rate can be calculated more accurately, reducing the error caused by discrete or irregular curves. In addition, a weight algorithm is used to comprehensively evaluate the average flow rate at different slope angles, so that the fluidity index can more accurately reflect the flow behavior of mortar as the slope changes.

[0111] In some embodiments, the trapezoidal integration algorithm includes:

[0112]

[0113] Among them, D total is the total flow distance, D i is the flow distance at the i-th time point, T i is the flow distance at the i-th time point, and n is the total number of data points;

[0114]

[0115] Where V is the average flow rate, T total is the total flow time;

[0116] The fluidity index of the mortar obtained by evaluating the fluidity of the mortar by a weighting algorithm based on the average flow rate at each current slope angle includes:

[0117] The average flow rate at each current slope angle is normalized, and the flow rate normalization formula is:

[0118]

[0119] Among them, V j标 is the normalized flow rate, V j is the average flow velocity at the jth slope angle, V min and V max are the minimum and maximum values ​​of the average flow rate under all current slope angles, respectively;

[0120] Based on the weights of each current slope angle, the fluidity index of the mortar is calculated, and the calculation formula of the fluidity index is:

[0121]

[0122] Among them, FI is the fluidity index of mortar, ω j is the weight corresponding to the average flow rate at the jth slope angle.

[0123] By measuring the fluidity of the mortar at multiple slopes and obtaining the final fluidity index of the mortar, the fusion of flow characteristic data at multiple dimensions and angles can more effectively reflect the performance of the mortar under different environments and different construction requirements, and provide a basis for the formulation of a more scientific construction plan. In addition, the average flow rate obtained at each slope angle is standardized, and then the fluidity index is calculated based on the preset weight, so that the test data are comparable, reducing the differences caused by different measurement environments or benchmarks.

[0124] In some embodiments, the water retention rate is calculated as follows:

[0125]

[0126] Where P is the water retention rate, W0 is the initial weight, W d For hardening weight.

[0127] In some embodiments, the comprehensive evaluation based on weights is performed based on the fluidity index, the water retention rate, the critical slope angle, and the bonding strength to obtain the comprehensive performance of the mortar, including:

[0128] For the fluidity index and the water retention rate, suitable intervals or target ranges are set respectively, and scores are given according to the degree of deviation between the measured value and the target range. The greater the degree of deviation between the measured value and the target range, the lower the score;

[0129] The values ​​of critical slope angle and bond strength are directly taken as fractions;

[0130] Normalizing the fluidity index, the water retention rate, the critical slope angle, and the bond strength score;

[0131] Based on the normalized values ​​of the fluidity index, the water retention rate, the critical slope angle, and the bonding strength and the preset weights, a comprehensive performance index of the mortar is calculated, and the comprehensive performance index is used as a comprehensive performance evaluation result of the mortar.

[0132] In some embodiments, the scores of the flowability index and the water retention rate include:

[0133]

[0134] Among them, Score FI / P is the score of the fluidity index or the water retention rate, δ is the distance of the deviation interval, l is the deduction coefficient, L is the lower limit of the suitable interval, U is the upper limit of the suitable interval, δ can be set manually, and l can be obtained based on historical data, experience values, or set manually.

[0135] Since the mortar needs to have a certain fluidity during construction, too low will make it difficult to spread, and too high will cause problems such as sagging and collapse. Therefore, the fluidity of the mortar needs to be kept within a reasonable range. The water retention rate also has similar problems. The water retention rate reflects the water retention capacity of the mortar. Too low water retention rate can easily lead to excessive water loss during construction, rapid shrinkage or cracking of the mortar; too high water retention rate may cause poor hardening in the later stage, so the water retention rate also needs to be kept within a reasonable range. In addition, the larger the critical slope angle, the more stable the mortar can remain during large inclinations or vertical construction, and the higher the bond strength, the stronger the bond between the mortar and the base. Therefore, the higher the critical slope angle and bond strength, the better the performance of the mortar, which can be directly used as the evaluation score.

[0136] The embodiment of the present application sets different evaluation methods for different indicators, and organically integrates the four key parameters of fluidity, water retention rate, critical slope angle and bonding strength into the same evaluation system, which is conducive to the experimenters to have an intuitive understanding of the comprehensive performance of the mortar, and can provide a scientific decision-making basis for material formula development and construction process adjustment.

[0137] In some embodiments, the calculation formula of the comprehensive performance index is:

[0138]

[0139] Among them, S is the comprehensive performance index of mortar, ω FI is the weight of the liquidity index, is the normalized value of the liquidity index, ω P is the weight of water retention rate, is the normalized value of water retention rate, ω θ is the weight of the critical slope angle, is the normalized value of the critical slope angle, ω Bis the weight of the bond strength, is the normalized value of the bonding strength.

[0140] In some embodiments, the weight of each indicator can be: FI =0.3;ω P =0.2;ω θ =0.25;ω B =0.25.

[0141] By using the weighting method to calculate the comprehensive performance index of various indicators, the quantitative analysis of the overall construction performance of mortar under different construction requirements or material formulation conditions can be achieved, providing data support for the formulation of targeted construction plans and material modifications.
