FIELD: construction.
SUBSTANCE: concrete contains the hydraulic binder - portland cement, fine aggregate - sand, mineral expanding additive "IR-1", coarse aggregate from Novocherkassk thermal power plant waste slag, which is a coal combustion product (slag) of Kuznetsk coal basin, extracted from the section "Kaltansky" with a bulk density of 650-700 kg/m3 with the following fineness ratio: fr. 5 mm - 47.5%, fr. 7.5 mm - 35.5%, fr. 10 mm - 17.0%, micropores and mesopores ratio 3.5:1 and the total pore volume according to water is not less than 0.6 cm3/g, while the water cement ratio is 0.5-0.6.
EFFECT: strength increase.
