FIELD: manufacture of building materials.
SUBSTANCE: process comprises preparing raw mix, drying molded green brick, and firing it. When preparing raw mix, clay stock with moisture content 18.0-21.0%, activated sludge sediment with total moisture 65%, and additionally ashes obtained upon burning of activated sludge sediment (moisture content 0%) are mixed to form homogeneous process-destined raw mix with density 15.0-21.0%. Ceramic brick manufacture process variations are described.
EFFECT: improved manufacture technology, reduced power consumption, reduced environmental pollution, and improved heat-insulation properties of brick.
