CONCRETE MIXTURE 'BIOMIN'

摘要

FIELD: building industry and materials.;SUBSTANCE: invention relates to compositions of concrete mixtures used for making underground constructions, wall blocks, enclosing and self-carrying building constructions and making wall made of monolith concrete in low building. Concrete mixture comprising cement and buckwheat husk and ground as filling agents, additive and water involves also ground with natural moisture with particles of size 0.1 mm and the content of argillaceous particles 30%, not above, and superplasticizing agent C-3 as additive in the following ratio of components, mas. p. p.: cement, 1; indicated ground, 2-4; buckwheat husk, 0.6-1.0; superplasticizing agent C-3, 0.01, and water, 0.4-0.6. Invention provides reducing heat conductivity coefficient, sufficiently high strength, enhanced economy and ecological property of concrete.;EFFECT: improved and valuable properties of concrete.;1 tbl
