FIELD: construction materials.
SUBSTANCE: invention can be used for production of polystyrene concrete articles with heat-insulating, heat-insulating-structural and structural-heat-insulating properties. Nanomodified polystyrene-concrete mixture contains the following components (per 1 m3 of the mixture): portland cement—85–300 kg; inert aggregate in form of construction sand with fineness modulus from 0.7 to 1.5 mm—0–140 kg; tripoli, or gaize, or diatomite, or mixture thereof, or flue ash—30–130 kg; amorphous nanosized silicon dioxide—0.05–0.9 kg; foamed granulated polystyrene—0.750–1.050 m3; fluffed chrysotile-asbestos fiber—1.2–8.2 kg; plasticising additive S-3—0.2–1.8 kg; 10% polyacrylamide solution—0.3–0.5 kg; saponified wood resin or neutralized air-entraining resin—0.01–0.2 kg; water—55–170 l.
EFFECT: invention enables to obtain a polystyrene-concrete mixture of a homogeneous structure with given strength and with given heat-insulating properties for articles with density in a dry state of 150–600 kg/m3.
