BINDING MATERIAL Russian patent published in 2008 - IPC C04B12/04 C04B7/28 

FIELD: construction.

SUBSTANCE: invention pertains to production of construction materials and can be used in industrial construction when making products and structures from acid resistant concrete. The binding substance consists of 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 - liquid glass, made from heavy wastes of ferrosilicon production in the Bratsk ferro-alloy factory - microsilica, containing 9 mass.% of fine-grained impurities in form of graphite - C, with a silicate module n=1-3 and density p=1.25-1.27 g/cm³ with the following ratios of components in mass.%: the said liquid glass 37.50-61.54, the said flue ash 38.46-62.50.

EFFECT: increased acid resistance of the binding material with simplification of its production process at the same time.
