FIELD: production of cellular materials; manufacture of building materials.
SUBSTANCE: proposed raw mixture contains the following components, mass-%: carbonized loam, 72.5-83; micro-silica, 9.7-14; burnt clay, 4.8-9.4; tall pitch, 2.1-3.4; sodium carbonate , 0.4-0.7. Proposed method includes preparation of mixture by mixing the micro-silica, tall pitch in form of emulsion in the amount of 0.9-1.5 mass-% with carbonized loam, burnt clay and water followed by introducing 1.2-1.9 mass-% of tall pitch in form of technical foam obtained by air bubbling of emulsified tall pitch.
EFFECT: extended functional capabilities; reduced average density, heat conductivity and usage of materials.
