FIELD: chemistry.
SUBSTANCE: invention refers to manufacturing ceramic bricks with a thinning agent and can be used in industrial and civil engineering. A raw mix for ceramic brick manufacturing contains clay and a thinning agent; the thinning agent represents ash having a particle size of no more than 2.5 mm and produced by burning of mixed bark waste and recovered stock, which is sediment of mechanic and biological treatment of pulp and paper waste water in the following ratio, wt %: clay 90-97, the above ash 3-10. The mixed bark waste and recovered stock have the following composition, wt %: bark 50-55, waste wood and saw dust 20-25, woodchips and woodchip waste 10-15, anhydrous recovered stock 10-15.
EFFECT: manufacturing of ceramic products meeting the requirements specified in State Standard (GOST) 530-2012, with reducing a man-caused load on environmental objects, extending raw material base, recycling bark waste and recovered stock.
