CALCIUM-SILICATE WATER GLASS HARDENER FOR THE FORMATION OF WATER RESISTANT ALKALI-SILICATE INSULATION MATERIAL
The authors show the possibility of the replacement of sodium fluosilicate to the water glass hardeners of calcium-silicate composition for the production of alkali-silicate thermal insulation materials according to the technology of cellular concrete. The proposed hardeners, in contrast to sodium fluosilicate, do not possess toxicity, and they also ensure the higher water resistance of final foam materials at equal densities.
