Abstract
The article presents the results of a comparative analysis of the axial tensile strength of masonry made of autoclaved cellular concrete blocks with cement mortars of various grades and polyurethane adhesive compositions of various manufacturers. The tests were carried out on prototypes made of two cubes of 150x150x150 mm glued together. As cellular concrete, blocks of autoclaved hardening of the compressive strength class B1.5, B2.5, B3.5 were used. M200 and M300 cement mortars, "Tytan Professional”, "Technonicol", "Bonolit" and “KUDO” foamed polyurethane glues were used as a binder. The experiment was performed in the Laboratory of the Department of Reinforced Concrete and Masonry Structures of the Moscow State University of Civil Engineering. On the basis of the experiment, the values of the increase in the strength of the masonry under axial tension were obtained depending on the binder.
