FIELD: construction.
SUBSTANCE: invention relates to building construction elements. Element is made of a cured mixture containing the following components, wt. %: dispersed foam glass - 60–85; 25–30 % alumina solution in orthophosphoric acid - 13–34; basalt microfiber - 2–6; fulleroid type carbon torus-like nanoparticles (fractions from 15 to 150 nm) - 0.009–0005. Mixture is cured at a temperature of 160–180 °C. Dispersed foam glass is made in the form of foamed glass beads, on the surface of which a layer of polyparaxylylene 2–5 microns thick is applied.
EFFECT: technical result consists in increasing the strength, toughness, crack resistance and durability at low density.
