To conduct control tests of masonry for adhesion of mortar to brick at the facility, a section of the outer wall was selected, where tests were carried out in accordance with the requirements of GOST 24992-81 “Stone structures. Methods for determining the adhesion strength of masonry. The adhesion test was carried out on five masonry bricks of the wall. The test results showed the arithmetic mean value of the ultimate adhesion strength in axial tension equal to 1.7 kg/cm2 (1.9; 1.7; 1.6; 1.6; 1.7).
