FIELD: construction. ^ SUBSTANCE: invention pertains to production of construction materials and can be used in the construction industry when making products and structures from acid resistant concrete. The binding material contains an aluminosilicate component - II field flue ash, obtained from burning brown Kansko-Achinskiy coal on Steam power plant -7 in Bratsk in the Irkutsk region and an alkaline component - carbon containing liquid glass, made from heavy wastes of ferrosilicate production from the Bratsk ferro-alloy factory - microsilica, containing 17 mass.% of fine-grained carbon-bearing impurities - graphite - C and silicone carbide SiC, with a silicate module n=1-2 and density p=1.40 g/cm3, with the following ratios of components in mass.%: the said carbon containing liquid glass 35.90-44.00, the said flue ash 56.00-64.10. ^ EFFECT: increased acid resistance of the binding material with simplification of the process of making it at the same time. ^ 2 tbl, 1 ex |
