FIELD: manufacture of building materials.
SUBSTANCE: invention relates to building materials with low heat conductivity and density values. Preparation of blend comprises stirring glass-forming components and powderlike additives containing gasifier among other components. Glass-forming component utilized is sodium and/or potassium silicate aqueous solution taken in amounts 50 to 70% and silicate-reactive additive is fine powder of broken glass. Stirring is carried out at temperature not superior to 70°C and viscous-flow mix is thermally treated at 450-550°C to completely remove of water, including chemically bound one, after which mix is cooled and ground into power with particle size at most 60-70 μm.
EFFECT: improved heat-engineering characteristics at low power consumption.
