CERAMIC COMPOSITION FOR MAKING BRICK Russian patent published in 2016 - IPC C04B33/132 

FIELD: technological processes; construction; ecology.

SUBSTANCE: invention relates to ceramic materials industry, primarily to compositions of mixtures for making ceramic bricks. Disclosed ceramic mixture contains beidellite clay, ash-slag material and electrothermal phosphorous slag containing, MP: SiO₂ - 43.65; CaO - 47.3; MgO - 2.2; Fe₂O₃ - 1.28; P₂O₃ - 2.4; Al₂O₃ - 2.67; SO₃ - 0.33; R₂O - 0.17, in the following proportions, MP: beidellite clay - 50-70; ash-slag material - 15-25, said electrothermal phosphorous slag - 15-25.

EFFECT: use of industrial raw materials in production of ceramic bricks contributes to recycling of industrial wastes, environmental protection, expansion of raw material base for ceramic materials; increases frost resistance of ceramic bricks to 84-87 cycles.
