Abstract:

The article presents information on a test experiment for the construction of masonry fragments made of autoclaved cellular concrete products (ААС blocks) on the polyurethane adhesive and the ensuing structural, thermal and technological tests of this type of masonry in specialized laboratories and testing facilities. It is shown that the use of polyurethane foam adhesive to bond the concrete blocks in the masonry walls is technically and economically feasible. On the basis of the tests it was concluded that the laying of concrete blocks on the polyurethane adhesive may be used in the construction of non-load bearing interior and exterior walls of buildings, including the filling of the external frame openings of monolithic buildings with floor bearing of the masonry on load bearing monolithic floors (with appropriate justification of the settlement).
