Abstract
The results of experimental studies of the tensile strength of the bandaged seam of walls masonry made of autoclave-hardened cellular concrete blocks are presented. A description of the installation for testing wall fragments for loads that simulate temperature effects that occur in buildings made of stone materials is given. There is no research in the effect of temperature impacts on the masonry of the walls made of cellular concrete blocks reinforced with composite grids based on basalt fiber. The results of tests for normal adhesion of cellular concrete blocks in the case of using an "AeroStone" adhesive mixture are presented. According to the results of tests of wall fragments on the load that simulates temperature effects, the effect of using a composite mesh based on basalt fiber of the "NOVAGRID" brand during axial stretching of the masonry along the bandaged seam was noted. Schemes of destruction of samples of masonry with composite mesh reinforcement and without reinforcement are presented, as well as values of destructive loads for each of the structural schemes are given. On the example of the analysis of the results of experimental studies of fragments of walls made of cellular concrete blocks, the effectiveness of using the NOVAGRID composite mesh when it is used as a reinforcement for the perception of horizontal tensile forces arising in the masonry is shown.
