AbstractAbout AuthorsReferences
The article presents the results of experimental studies to determine the strength of normal adhesion (when axial tension) in the masonry of cellular concrete blocks of autoclave hardening of compressive strength B1.5–B3.5 classes on the most common cement and polymer cement (adhesive) mortars. The tests were carried out by the laboratory of the Department «Reinforced Concrete and Stone Structures» of the Moscow State University of Civil Engineering on experimental samples representing two cubes of 150х150х150 mm, sawn from cellular concrete blocks and bonded (glued) together with masonry mortars. The analysis of research results is conducted and the conclusion is made about the increase in normal adhesion in the masonry made from cellular concrete blocks autoclaved hardening of compressive strength B2.5, and B3.5 classes when using polymer compositions instead of cement mortars in masonry joints.
