## 3 Results and Discussion
The polynomial Equations (5)-(11), obtained by interpolating the experimental data, show the relationship between the processing time in the VLA (\(t\)) and the strength and deformation characteristics of lightweight fiber-reinforced concrete (\(R_{b,cub},R_{b},R_{btb},R_{bt},\,\epsilon_{b},\,\epsilon_{bt},\,E\)) together with the coefficient of determination (\(R^{2}\)):  
\[R_{b,cub}=(-8E-5)\ t^{3}+0.0089t^{2}+0.1978t+23.146,\ R^{2}=0.9839 \tag{5}\]  
\[R_{b}=(-1.0E-4)t^{3}+0.0027t^{2}+0.1077t+48.033,\ R^{2}=0.9804 \tag{6}\]  
\[R_{btb}=-0.0021t^{2}+0.3575t-4.728,\ R^{2}=0.7758 \tag{7}\]  
\[R_{bt}=-0.012t^{2}+0.1951t-1.8571,\ R^{2}=0.7998 \tag{8}\]  
\[\epsilon_{b}=-0.0001t^{2}+0.0216t+2.1286,\ R^{2}=0.8133 \tag{9}\]

Figure 6:0 Dependence of the prismatic compression strength of lightweight fiber-reinforced concrete specimens on the processing time of CSM in VLA. Figure 6:1 Dependence of the tensile strength in bending of lightweight fiber-reinforced concrete specimens on the processing time of the CSM in VLA. Figure 6:2 Dependence of ultimate deformations during axial compression of lightweight fiber-reinforced concrete specimens on the processing time of CSM in VLA. Figure 6:3 Dependence of the axial tensile strength of lightweight fiber-reinforced concrete specimens on the processing time of the CSM in the VLA. The above values of the coefficients of determination show a good relationship between the regression curve and the data points of the processing time in the VLA and the test results.

Figure 6:5 Dependence of the modulus of elasticity of lightweight fiber-reinforced concrete samples on the processing time of CSM in VLA. According to the results of the experimental studies, the optimal processing time for the cement-sand mortar in the VLA apparatus is 75-85 s.  
In studies [6; 7; 8; 9; 18; 19; 31; 32; 33], activated cement, or activated mortar part was intended for heavy concrete and aerated concrete; in particular, this is shown in the works of the authors of the scientific school under the leadership of [PERSON] [34]. Our research is based on some of the results obtained by these authors and develops it in the direction of new types of technology and materials. To assess the efficiency and rationality of our proposed solutions, we will compare our results with the results obtained earlier by other authors. This article defines an effective technology and electromagnetic activation parameters in the vortex layer devices of lightweight fiber-reinforced concrete components. In comparison with previous works [31; 32; 33], it was found that even a short activation time of 75-85 s leads to a significant result. In particular, the increase in strength reaches more than 60%. This significantly exceeds the previously proposed methods [31; 41; 42] and has the advantage, first, for its short duration, and second, for low resource and labor costs; the efficiency of strength gain is also significantly higher. The effect is especially highlighted in relation to lightweight concrete. At the same time, we strengthened the effect by the fact that concrete has dispersed reinforcement, therefore, the proposed technology helps to increase the effect not only in strength but also in deformability, which increases the operational reliability and operational possibilities of using the improved material developed by us.
