COMPOSITION OF FORMING-MIXTURE FOR SULFOPOR HARD PLASTER

摘要

This invention pertains to industry of construction supplies and to field of building. It could be used for producing prefabricated constructions of outer walls and inner walls, for making heat insulation articles as well as for making cast-in-situ concrete. Composition of forming-mixture for sulfopor hard plaster comprises prefabricated dry mixture of binder that contains alpha-form of gypsum hemihydrates and insoluble calcium sulphate anhydrite by following weight-ratio of ingredients (in mass-units): binder containing gypsum alpha-hemi hydrate (alpha-CaSO4 . 0.5 H2O) 85 - 40; disperses particles from alpha-calcium soleplates dihydrate (alpha-CaSO4 . 2 H2O) 5 - 30; condensation products of formaldehyde and organic substance, for example, melamine or naphthalenesulfonic acid, or salts thereof 0.3 - 0.5; oxide or hydroxide of alkali metal 0.2 - 0.6; catalyst - manganese chloride 0.005 - 0.02; hydrogen peroxide (solution, approximately 25%) 0.2 - 0.4.
