FIELD: construction.
SUBSTANCE: invention relates to compositions of mixtures for making ceramic bricks. Ceramic mixture contains the following components, wt%: beidellite fusible clay 50-70; ash-slag material 15-25; wastes of gold ore deposit 15-25. Wastes of gold ore deposit have following composition, wt%: SiO2 - 62.63; Al2O3 - 17.18; Fe2O3 - 7.84; CaO - 1.2; MgO-1.15; R2O - 6.6; ignition loss - 3.4.
EFFECT: technical result is increasing in frost resistance of brick.
