FIELD: chemistry.
SUBSTANCE: invention relates to compositions for protective coating of surfaces of concrete structures, relating to building materials. The composition includes a film-forming base and additionally contains graphite with weight ratio of latex to graphite equal to 1:(0.05-0.14). The film-forming base used is synthetic latex selected from a group comprising latex based on copolymers of butadiene and styrene, based on vinyl acetate, based on styrene and acrylic esters. Alternatively, the film-forming base used in the composition can be an aqueous solution of a sodium salt of carboxymethyl cellulose with concentration of 2-5 wt % and Brookfield viscosity of 7-15 MPa·s.
EFFECT: reduced wearing of metallic elements sliding on the surface of the concrete structure.
