Experimental Determination of Normal and Shear Adhesion in the AAC-Blocks Masonry at Various TLM Adhesive Compositions

In 2013–2014, Laboratory of seismic stability of structures of the Research Center of Earthquake Resistance of Structures of TSNIISK named after V.A. Kucherenko (JSC Research Center of Construction) by the order of the National Association of Autoclaved Aerated Concrete Producers executed the work on “Experimental determination of normal and shear adhesion of mortars and adhesive compositions, laid by thin layers, to cellular concrete blocks of autoclaved hardening”. Masonry joints of up to 2 mm thickness formed by three types of cement mortars for the thin-layer masonry and a layer of polyurethane assembly adhesive have been studied in this work. Joints in the masonry made of cellular concrete of autoclaved hardening of 300–600 kg/m³ density and 1.7–7.3 MPa strength have also been studied. By results of studies, it is established that the masonry of the first category (with a tensile strength along the non-tied section 180 kPa) can be made of blocks of B1.5 strength).
