Abstract: FIELD: manufacture of building materials; applicable in production of foamed silicate material of various kinds and forms - granules, etc, which are applicable, both, individually, and also as components in manufacture of such products as laminated wall or roof panels. SUBSTANCE: method for production of foamed silicate material includes preparation of mixture of water glass and an additive in the amount of 0.1-8.5% of the water glass mass. Additive is used in form of, at least, one substance from the group including vegetable oil, substance based on dicalcium silicate, fiber filler of polyethylene film and copper vitriol, with subsequent introduction of ethanol in the amount of 9-11 vol.p. per 100 vol.p. of water glass. Produced mixture is placed into mold and compacted at pressure of 20-60 atm with removal of excessive liquid, held for 24 h. Obtained material is foamed in super-high frequency furnace at the volumetric density of radiation power of 40 kW/l and frequency of 2.45 GHz for 20-25 min. Prior to placing the mixture into mold, poured into mold is foamed silicate material ground to size of 0.5 mm, preferably, 0.1 mm in a layer of 1-2 mm thick. Method also provides for use of vegetable oil in the amount of 0.3-1.5% of the water glass mass, substance based on dicalcium silicate - ferrochromium slag or nepheline slime in the amount of 0.3-1.5% of the water glass mass, fiber filler from polyethylene film 100 mcm thick, 1-2 cm long in a layer 0.5-1.0 mm thick in the amount of 1-5% of the water glass mass, copper vitriol in the amount of 0.1-0.5% of the water glass mass. Placed into mold prior to and/or after placing of the mixture on the molding surfaces is textile fabric. The surface of the produced material is coated with water-repelling agent by precipitation. Product material may be placed into polyethylene film. Also possible is to cut the material, after holding, into products of the required size with consideration of its 20-25-fold volume expansion. Removed excessive liquid during compaction is subjected to distillation, and separated ethanol is used for mixing with water glass. Water glass is used in form of that produced by dissolving silicate block or by direct synthesis from quartz sand and alkali component. Method provides for the following characteristics of the produced material: density 50-80 kg/cu.m; heat conduction 0.035-0.04 W/mK, thermal stability up to 550 C, compression strength 0.5 kg/sq.cm, daily water absorption from the ambient air with humidity above 85% less than 0.1%, and in water for 24 h - 10-15%.
