FIELD: building.
SUBSTANCE: invention refers to building materials, particularly to compositions of concrete. The concrete mixture contains, wt %: slag-Portland cement of M500 grade 15-18, slag filler - crushed blast furnace slag of 0-15 mm size 50-60, and complex additive "Relamix" of Type "2" 0.1-0.3 and the rest is mountain sand of composition, wt %: SiO2 34.1-39.9; Al2O3+TiO2 9.8-11.0; FeO+Fe2O3 12.8-26.1; CaO 11.3-13.7; MgO 4.2-5.7; MnO 0.3-0.55; P2O5 0.5-0.6; SO3 1.7-3.2; Na2O+K2O 1.3-3.2; l.a.f. (losses after firing) 8.5-15.0, containing 20-30% of garnet minerals.
EFFECT: increased bending and compression strength, moisture and frost resistance of concrete.
