CERAMIC MASS FOR PRODUCTION OF BUILDING BRICK Russian patent published in 2022 - IPC C04B33/16 C04B33/132 

FIELD: building materials.

SUBSTANCE: invention relates to the production of building materials. Ceramic mass for the production of building bricks is proposed, containing (wt.%): low-melting clay (75-84.5), chamotte (2.0-3.5), sand (10-15), and it contains peat of 0.5-5 mm (2.0-3.5) fraction and non-calcined precipitates of chemical water treatment formed at thermal power plants (1.5-10) as burnout and thinning additives.

EFFECT: addition of peat of 0.5-5 mm fraction and non-calcined precipitates of chemical water treatment of thermal power plants in the production of products from clay raw materials provides the possibility of optimal conditions for structure formation, contributes to the reduction in the firing temperature, more uniform drying in the entire volume of bricks, reduction in stresses arising during drying, which determine an increase in physical and mechanical properties of ceramic products; the firing temperature is also decreased, the frost resistance of finished products is increased, and the cost of manufacturing ceramic bricks is decreased by 10%.
