NON-FIRED HEAT-INSULATING MATERIAL ON BASIS OF BERGMEAL OF SUKHOLOZHSKY FIELD OF SVERDLOVSK OBLAST

摘要

FIELD: construction.SUBSTANCE: non-fired heat-insulating material made from the mix comprising a binder, PB-2000 frother and water where the binder of the mix is the suspension obtained by mixing of the bergmeal ground to the specific surface 2000 m/g, 40% solution of caustic soda and water in a weight ratio 1:1.34:3.10, holding at 95°C within 4 h and cooling, and in addition - sodium silicofluoride and microsilica at the following ratio of components, wt %: the named suspension 68.0-74.0, sodium silicofluoride 5.2-6.0, PB-2000 frother 0.38-0.42, microsilica 3.6-4.8, water - the rest.EFFECT: producing of wall materials using the simplified technology and local raw materials.3 tbl
