Annotation: In the given work there are given the results of technological factors influence on the properties of bloating inorganic coverings of aluminum silica composition. It has been shown, that most rationally to realize the layering puthing the fire-resistant bloating compositions with filling degree from 5 up to 35 % from the binding mass, received on the basis of alkaline silica-aluminum binding kind (1,09-1,7) Na2O•Al2O3•(6,64-8,42)•SiO2•(22,16-35,76)•H2O and (1.56-2.48) ) Na2O•Al2O3•(7.6-10.19)•SiO2 (23.27-43.06)•H2O by the filling the air method. While such a method using of covering the metal warning does not exceed 200-250оС with the covering thickness from 2 up to 4 mm. The introduction the bloating fireproof silica-aluminum compositions into the calcium carbonate which is dissolved at the temperature 800-830оС and educes CO2, and increases the share of the filler stimulated the enhacing the resistant time of the flame up to 54 minutes. To achieve the fire resistance up limit to 60 of the bloating inorganic coverings of silica-aluminum composition it is necessary to use the way of silica-aluminum binding a modification and to apply above marked way of covering putting.
Keywords: fireproof bloating alkaline silica-aluminum compositions, filler silica-aluminum composition, bloating factor, temperature of heating of a metal substrate, standard curve of distribution of a fire.
