FIELD: chemistry.
SUBSTANCE: invention relates to production of construction materials. Raw material mixture for production of silicate bricks includes, wt %: ground for specific surface 3500-4000 cm2/g quartz sand 70-85, powder of water purification sludge, formed as a result of extraction of rigidity salts during water preparation on thermal stations, with bulk density 850-900 kg/m3 5-25, ground live lime 5-10.
EFFECT: increased water resistance and reduction of autoclave processing duration.
