FIELD: chemistry.
SUBSTANCE: invention relates to structural materials and can be used to make articles from nanomodified concrete in both civil and industrial construction. The nanomodified concrete contains portland cement, sand, water, a nanoadditive, a superplasticiser, wherein the superplasticiser used is a Relamix additive and the nanoadditive is nanosilica sol, microsilica and white soot, with the following ratio of components, wt %: portland cement 24.7-25.0, sand 65.3-65.43, nanosilica sol 0.0025-0.0028, microsilica 1.24-1.3, white soot 0.025-0.028, Relamix superplasticiser 0.2-0.21, water 8.4-8.8. The method of producing nanomodified concrete includes mixing in a dry state portland cement, sand, white soot, microsilica and 2/3 water and then adding the Relamix superplasticiser, nanosilica sol, 1/3 of the remaining water, followed by final mixing.
EFFECT: high strength and low water absorption of the concrete.
