HIGH-STRENGTH CONCRETE Russian patent published in 2017 - IPC C04B28/04 C04B14/26 C04B18/08 C04B24/24 

FIELD: construction.

SUBSTANCE: high-strength concrete of mixture comprising Portland cement, quartz sand, granite breakstone, an integrated filler, an additive and water, in which the sand is represented by the quartz sand with the fineness modulus of 2.2, the breakstone - by the granite breakstone with the fraction of 5-20 mm, the integrated filler - by the integrated filler with the specific surface of 320 m²/kg, consisting of limestone and electrofilter ash at the following ratio of components, wt %: limestone 10-15; electrofilter ash 85-90; and the additive is represented by the water solution with the density ρ=1.032 g/cm³ and the hydrogen index pH=5,5, consisting of a polycarboxylate polymer based on methacrylic acid with the density ρ=0.95 g/cm³ and the hydrogen index pH=7.0; a polycarboxylate polymer based on allyl ether and maleic acid anhydride with the density ρ=1.03 g/cm³ and the hydrogen index pH=7.0; 40% aqueous solution "Russian glyoxal", calcium chloride and water at the following ratio of components, wt %: the polycarboxylate polymer based on methacrylic acid with the density ρ=0.95 g/cm³ and the hydrogen index pH=7.0 - 10.0-17.0; the polycarboxylate polymer based on allyl ether and maleic acid anhydride with the density ρ=1.03 g/cm³ and the hydrogen index pH=7,0 - 13,0-17,0; 40% aqueous solution of "Russian glyoxal" - 3.5-4.0; calcium chloride 5.5-7.0; water - 61.0-62.0, with the following ratio of components of high-strength concrete, wt %: Portland cement - 13.5-16.0; said sand - 31.0-31.5; said breakstone - 45.03-46.53; said filler - 1.23-1.43; said additive - 0.13-0.14; water - 6.61-6.9.

EFFECT: increasing waterproofness.
