FIELD: chemistry.
SUBSTANCE: invention relates to production of construction materials, specifically to production of water glass-based expanded aggregates, intended for manufacture of lightweight concrete, and fill insulation materials. Composition for manufacture of the expanded aggregate comprises as follows, wt %: sodium water glass with a density of 1.41 g/cm3 50-75, sodium chloride, ground to a particle size below 0.3 mm 1-3, burnt rock, ground to a particle size below 0.14 mm 12-34, drill cuttings, ground to a particle size below 0.14 mm, and oxides, wt %: SiO2 - 26.2; Al2O3 - 4.5; Fe2O3 - 5.6; CaO - 28.3; MgO - 1.2; R2O - 0.8; ignition loss - 33.4, 10-15.
EFFECT: composition for manufacture of expanded aggregates, with improved compression strength and softening temperature, industrial waste recycling.
