Abstract

Interaction of polyorganosiloxanes of different spatial structures with polymethylmethacrylate and epoxide resin in different ratios was investigated, namely double and triple systems were considered in the paper. The obtained systems were used in modifying the cellular concrete surface and identifying the main physical and mechanical properties such as surface adsorption, impregnation depth, water absorption, ultimate bending strength.

Modifying the surface of cellular concrete was conducted to improve its performance properties since at the large number of open capillary pores during operation in outdoor conditions, products lose their basic feature − heat insulating. Also, modified products have a 5 times higher ultimate bending strength.

As a result of studies, it was found that impregnations, based on silicone varnish KO-075 were the most effective modifying compositions. They united 2 principles at once: surface hydrophobization with its simultaneous strengthening. The obtained data are of great interest for both researchers and cellular concrete products manufacturers. Modified

cellular concrete products can be used as supporting structures in low-rise construction that in turn will lead to saving energy and labor costs.
