FIELD: chemistry.
SUBSTANCE: invention relates to the industry of construction materials and more specifically to compositions of concrete mixtures used in making precast and monolithic reinforced concrete structures. The concrete mixture, which contains portland cement, quartz sand, mineral fibre and water, contains mineral fibre in form of basalt fibre with diameter of 13-17 mcm and length of 6-12 mm, and additionally contains superplasticiser Polyplast SP-4, with the following ratio of components, wt %: portland cement - 28-30, quartz sand - 56-60, said mineral fibre - 0.05-0.18, said superplasticiser - 0.12-0.18, water - the balance.
EFFECT: high compression strength and frost resistance of the concrete.
