СЫРЬЕВАЯ СМЕСЬ ДЛЯ ПРОИЗВОДСТВА СИЛИКАТНЫХ ИЗДЕЛИЙ
FIELD: chemistry.SUBSTANCE: invention relates to the field of building materials and can be used as a raw material for the production of silicate bricks, stones, blocks and slabs. Raw material mixture for the production of silicate products contains a limestone-siliceous binder with an activity of 35–40 % and a specific surface of 5,000–6,000 cm/g, obtained by the joint grinding of a mixture of quartz sand and limestone with an activity of 70–80 % in a ratio of 1:1, quartz sand with a size modulus of 1.1–1.3 and crushed aerated concrete with a density of 500–600 kg/mfraction 0–5 mm with a modulus of fineness 2.5 with the following ratio of components, mass%: limestone-siliceous binder 18, sand quartz 33–49, crushed aerated concrete 33–49.EFFECT: technical result is a decrease in density and thermal conductivity while maintaining high strength.1 cl, 2 tbl
