SU1278329A1 - Composition for construction work - Google Patents

Abstract

The invention relates to a composition for construction work and may find application in the concreting of monolithic floors, in brick and masonry, plastering and finishing works, and in the manufacture of structures that harden under normal conditions and during thermal and moisture treatment. The construction composition consists, in wt.%: Cement 14.216, 8, sand 60.3-62.6, plasticizing additive 1.17-6.8, containing a mixture of bauxite sludge and waste solution of sulfuric acid pickling of steel at a ratio (l4 : l)

The plasticizing additive is produced by a known technology. by mixing in a disintegrator the Cement, sand plasticizing the red-hot bauxite sludge - the waste is mixed together in the production of technical alumina during the process of mixing them with water into a mixture with a spent solution of a sulfur-burning plant. From this ground-glass pickling of carbonaceous sta- tions (a mixture of mixtures, cubes were made at a ratio of (14: 1) - (10: 1), with an edge of 7 "7" 7 cm, then the density of red sludge samples in air-dry and wet 1,24-1,8 and spent pickling conditions x.
