LIGHTWEIGHT CONCRETE Russian patent published in 2006 - IPC C04B38/08 

FIELD: construction materials industry; production of the lightweight concretes.

SUBSTANCE: the invention is pertaining to construction materials and articles, in particular, to the structural heat-insulating to lightweight concretes used for the walling constructions. The technical result of the invention is the increased density and strength at conservation of the materials thermal conductivity. The lightweight concrete, which includes the cement, the hollow microspheres and water additionally contains the silicon opal- cristobalite rock - flask at the following ratio of the components (in mass %): the cement - 24.9-29.3, the indicated flask - 11.8-20.2, the indicated microspheres - 29.8-35.1, water - the rest.

EFFECT: the invention ensures the increased density and strength of the lightweight concretes at conservation of the lightweight concrete products thermal conductivity.
