FIELD: chemistry.
SUBSTANCE: invention relates to the industry of building materials and can be used in manufacturing products in civil and industrial construction, monolithic construction and for erection of special-purpose structures. The high-strength light concrete made from a concrete mixture contains portland cement, filler, a plasticiser, water, a mineral part consisting of microsilica with average particle size of 0.01-1 mcm, rock flour - a product of grinding quartz sand with specific surface area of 700-800 m2/kg and quartz sand with grain size of 0.16-0.63 mm, with the following ratio of components, wt %: portland cement 33.8-53.0, microsilica 4.77-13.8, rock flour 1.5-11.9, quartz sand 5.1…32.2 , microspheres 4.3-19.27, plasticiser 0.3-0.48, water - the balance.
EFFECT: obtaining concrete with high specific strength.
