FIELD: construction.
SUBSTANCE: invention relates to production of construction materials and can be used to produce wall ceramics, in particular, ceramic bricks and stone. Technical result is achieved by optimizing the composition and preparation of the ceramic mixture, which includes fine dispersion of components to 200 µm fraction, followed by granulation of carbonic mudstone refuses and moderately plastic clay to 1–3 mm particle size in the following ratio, wt%: carbonic mudstone refuse – 70–80; moderately plastic clay 20–30.
EFFECT: technical result is increased compression strength (up to 2,3 times) and reduced maximum burning temperature of the ready products made from carbonic mudstone and clay refuses.
