AbstractAbout the AuthorReferences
Results of the experimental research in the shear and diagonal compression of stone masonry samples made of cellular­concrete blocks with thin­layer polyurethane joints are presented. On the basis of the experimental studies, peculiarities of the destruction of experimental samples have been revealed; values of the initial strength of the stone masonry at shear as well as values of the shear module and ultimate values of the angle of shear deformations of the stone masonry have been obtained. It is established that under the impact of shear load in the plane of horizontal polyurethane joints, the destruction of the masonry occurs as a result of exhaustion of strength of the block material for shear. The comparison of the results obtained with the results of the experimental study of the stone masonry made of cellular­concrete blocks with thin­layer polymer­cement joints is made. The difference in the nature of destruction of samples of stone masonry on the polymer­cement adhesive solution and on the adhesive foam as well as their strength and deformation characteristics at shear are shown.
