FIELD: construction.
SUBSTANCE: concrete mix, including cement, fine and coarse filler, mineralised drains with tempering water, containing calcium and sodium chlorides at the ratio of 1.01:1-1.4:1, besides, the number of drains in the composition of the concrete mix makes from 1 to 4% by active substance from the cement mass, according to the invention, it additionally contains an inhibitor of reinforcement corrosion - potassium bichromate K2CrO7 (PBC) - in the amount of 0.2-0.25% of the cement mass at the following ratio of components, wt %: portland cement - 15-19; sand - 23-27; crushed stone of fraction 5-20 mm - 47-49; specified mineralised drains - 0.15-0.76; specified corrosion inhibitor - 0.03-0.047; water - balance.
EFFECT: increased strength of concrete and provision of long-term corrosion resistance of reinforcement in reinforced concrete structures.
