FIELD: construction.
SUBSTANCE: the nanomodified concrete is obtained from a mixture of Portland cement, fractionated sand, water and nanoadditive presented by nanoscale silica with a specific surface area of 300 m2/g and a superplasticizer based on polycarboxylate ethers in the following ratio, wt %: Portland cement - 25.124-27.227; sand with a fraction of 5-2.5 mm - 6.126-6.239; sand with a fraction of 2.5-1.25, 0.63-0.315 and 1.25-0.63 mm - 15.316-15.6; sand with a fraction of 0.315-0.16 mm - 9.19-9.36; superplasticizer based on polycarboxylates ethers - 0.041-0.045; specified nanoadditive - 0.304-0.334; water - the rest.
EFFECT: Effect: increased compressive strength at the age of 28 days and improved durability of concrete due to protection from internal corrosion leakage of the concrete by reducing relative expansion deformations of it down to 0,04.
