FIELD: chemistry. ^ SUBSTANCE: invention relates to construction materials. The crude mixture for making wall and building stones through vibrocompression contains non-clinker slag-alkali binder and aggregate in form of sand, having the following composition in wt %: SiCb 34.1-39.9; Al2O3 9.8-11.0; FeO+Fe2O3 12.8-26.1; CaO 11.3-13.7; MgO 4.2-5.7; SO3 1.7-3.2; Na2O+K2O 1.3-3.2; percentage of other impurities 8.5-15; dry slaked boiler coal slag, additive - clay or saw dust, or microsilica or mixtures thereof with the following ratio of components, wt %: said binder 25-35, sand sand 5-15, said additive 3-15, said slag - the rest. Method of making wall and building stones from the said mixture involves tempering the said mixture with a solution which contains structured water and a polymer, placing into a mould, vibrocompression, removal from the mould and drying the stones. ^ EFFECT: high mechanical strength, homogenisation of the composition of concrete in the article, low density and thermal conductivity of building stones. ^ 2 cl, 2 tbl, 1 ex |
