FIELD: building materials.
SUBSTANCE: invention relates to the field of building materials and can be used in the manufacture of concrete products in civil engineering and construction of road and sidewalk surfaces. The concrete mix contains, wt.%: Portland cement CEM I 42.5N 22.14-22.47, quartz sand 67.42-68.44, niobium-titanosilicate additive 0.07-0.24, superplasticizer based on Glenium 51 polycarboxylate ether 0.025-0.035 and water - the rest. The niobium-titanosilicate additive contains, wt.%: 1-2 Nb2O5, 21.8-24.4 SiO2, 30.1-37.4 TiO2, 18.2-21.2 Na2O with a specific surface area of 120-165 m2/ G.
EFFECT: increasing the strength and ensuring self-cleaning of the concrete surface under both ultraviolet and visible radiation, as well as improving the abrasion resistance of concrete.
