CERAMIC MASS Russian patent published in 2017 - IPC C04B33/132 C04B33/14 

FIELD: construction.

SUBSTANCE: ceramic mass includes loam, expanded clay, an iron-containing additive and a burnable additive. As the iron-containing additive, a grounded ammonia production waste - a spent catalyst - is taken, and as a burnable additive - a liquid expanded polystyrene production waste (mother liquor), with the following ratio of the ceramic mass, wt %: loam 69.35-70.5 ; expanded clay 23-23.5; an iron-containing waste - ground spent ammonia production catalyst - to a specific surface area of 200 m²/kg 1.25-1.5; a liquid expanded polystyrene production waste with the density of 1.014 g/l 4.5-6.4.

EFFECT: increasing the product strength after drying, burning, reducing heat and power costs due to reducing the burning temperature, preserving the architectural appearance of products.
