CONCRETE MIXTURE Russian patent published in 2009 - IPC C04B28/08 C04B111/20 

FIELD: building.

SUBSTANCE: invention refers to building materials, particularly to cement-free compositions of concrete mixtures out of industrial wastes. The concrete mixture contains, wt %: ground steel-casting slag - 86-88, pulp-actuator produced at neutralisation of spent electrolyte of traction acid accumulators with lime - 7-8, burned rock of mine dumps - 5-6; also said slag and rock are ground together to specific surface 300-320 m²/kg.

EFFECT: utilisation of exclusively and generally available anthropogenic wastes of local industrial raw material base in composition of cement-free concrete mix; also said wastes do not require additional processing, notably, grinding to specific surface 400-450 m²/kg, special burning or heat treatment of source components, and change of production process, while achieving strength of not less 10 MPa (M 100) at 28 day age.
