CONCRETE MIXTURE Russian patent published in 2006 - IPC C04B28/02 C04B111/40 

FIELD: building industry and materials.

SUBSTANCE: invention relates to composites of concrete mixtures used in making underground constructions, wall blocks, protecting and self-carrying building constructions and making walls made of monolith concrete in low building construction. Concrete mixture comprises cement, filling agent, superplasticizer C-3, hydrophobizing organosilicon liquid GKZH-94 and water. As a filling agent the mixture comprises the soil of natural moisture with sizes particle less 0.1 mm, total surface above 62 m²/kg and the content of clay particles 30%, not above, in the following ratio of components, mas. p. p.: cement, 1; indicated soil, 2-4; superplasticizer C-3, 0.01; GKZH-94, 0.001, and water, 0,4-0.5. Invention provides preparing concrete with decreased average density and water requirement, low heat conductive coefficient, enhanced strength, high resistance to cold, change of deficit and expensive large filling agent (granite, lime) for landmark materials and enhanced elasticity of concrete that can be used in low building construction. Also, invention provides the improved ecology properties of concrete.

EFFECT: improved and valuable properties of concrete mixture.
