FIELD: construction.
SUBSTANCE: manufacturing method for acidproof concrete includes batching of compound and binding substance components, mixing thereof, products shaping by vibrocompression and their hardening in steam curing camera at temperature of T=90-95°C for 10 hours with the following holding of stripped steamed products for 14 days at humidity of W=100% and T=18-22°C. As compound, the ash and slag mix from dump at Irkutsk TPS-6, Bratsk, having packed density of p=1200-1250 kg/m3, grain size of 0.63-10.0 mm and humidity of 2% is used, as binding substance, ash-alkali binding substance is used which consists of fly ash of II field, got from combustion of Kansko-Achinsky brown coal at TPS-6, Bratsk, Irkutsk Region, and soluble glass - microsilica produced from heavy waste after ferrosilicon production of Bratsk ferroalloy plant.
EFFECT: concrete acid resistance improvement.
