CERAMIC MASS FOR PRODUCTION OF CONSTRUCTION BRICK Russian patent published in 2021 - IPC C04B33/04 C04B33/132 C04B33/16 

FIELD: building materials.

SUBSTANCE: invention relates to the field of building materials, namely the manufacture of ceramic bricks from a ceramic mass including low-melting clay, chamotte, sand, and uncalcined sediments of chemical water treatment formed at combined heat and power plants are used as a lean additive. Adding uncalcined sediments of chemical water treatment of combined heat and power plants in the amount of 5-10 wt. % in the production of products from clay raw materials contributes to a decrease in the firing temperature and the appearance of a melt, which leads to the crystallization of solid minerals from the melt and an increase in the amount of glass phase, which determines an increase in the strength properties of products. Ceramic mass for the production of building bricks, including low-melting clay, chamotte, sand, additionally contains, as a lean additive, uncalcined precipitation of chemical water treatment formed at combined heat and power plants, with the following ratio of components, wt. %: low-melting clay - 75-79; chamotte - 4-7; sand - 12-20; uncalcined sediments of chemical water treatment of combined heat and power plants - 5-10.

EFFECT: improvement of ceramic bricks manufacture method.
