RAW MATERIAL MIXTURE FOR MANUFACTURING CERAMIC BRICKS Russian patent published in 2017 - IPC C04B33/16 C04B38/06 C04B33/132 

FIELD: construction.

SUBSTANCE: raw material mixture for manufacturing ceramic bricks, including clay, quartz sand with the fineness modulus of 2.0-2.2, and a burn-out additive, additionally contains siliceous sludge waste of the processing process of the spent vanadium catalyst of sulfuric acid production, and as the burning additive, it contains the mixture of sawdust, rubber regenerate crumb of recyclable car tires processing, hydroxypropyl cellulose at the ratio of the indicated constituents of the burnout additive: 1:0.1-0.3:0.01-0.02 with the following component ratio, wt %: clay 73.0-87.0, mentioned quartz sand 9.0-16.0, sludge of the spent vanadium catalyst processing process 2.0-5.0, said burn-out additive 2.0-6.0.

EFFECT: increasing the physical and mechanical characteristics of ceramic bricks, including increasing the compressive strength and bending strength, eliminating the external defects of the front brick faces, increasing the thermal properties, reducing the cost and increasing the profitability of brick production.
