FIELD: process engineering.
SUBSTANCE: invention relates to production of construction materials and can be used for fabrication of ceramic bricks, stones and blocks. Proposed method comprises preparation of foam-ceramic mix from clay stock, water, foaming agent, binding agent, drying, annealing and forming. Note here that, additionally, foaming agent PB-2007 is admixed as a plasticising agent while finished product ground to 1.25-5.0 mm fraction or perlite sand are used as binding additive. Then, obtained mix is poured in flat moulds and dried, first, at 30-35°C and, then at 50-56°C to make an integral blank to be withdrawn from the mould, annealed at 800-1600°C and formed to blocks.
EFFECT: higher heat- and noise-isolation properties, decreased weight.
