FIELD: manufacture of building materials.
SUBSTANCE: invention is aimed at manufacturing ceramic bricks used mainly in construction of residential and industrial buildings. This aim is achieved by adding combustible additive - postalcohol distillery dregs (moisture content 19.2-19.8%) to mix consisted of Cambrian clay and mortar sand having fineness modulus 2-2.5. Resulting mix contains 70-80% Cambrian clay, 10-15% mortar sand, and balancing amount of distillery dregs.
EFFECT: enabled manufacture of ceramic bricks with reduced weight and heat conductivity at the same breaking point at compaction.
