FIELD: chemistry.
SUBSTANCE: concrete mix includes portland cement, aggregate, microsilica and water. The mixture contains highly active metakaolin, "Linamix PK" is taken as a superplasticiser with the following component ratio, wt %: portland cement - 19-20; medium natural sand - 67-68; microsilica - 0.8-1.81; highly active metakaolin - 0.5-1.08; superplasticizer "Linamix PC" - 0.1-0.2; water - the rest.
EFFECT: decreased content of calcium hydroxide in the composition, leading to a reduction in corrosion of type I and II, and increased strength due to the introduction of pozzolanic additives and superplasticiser to the concrete mixture.
