FIELD: construction.
SUBSTANCE: invention relates to compositions of ceramic mixtures for making bricks. Ceramic mixture for making brick contains, MP: clay - 96.7-97.7; coal - 1.0-1.5; crushed defective brick - 0.1-0.3; oil sludge - 1.0-1.5. Oil sludge is a product of cleaning of oil refineries' waste water. Mineral part of oil sludge is represented by polydisperse particles (MP): CaCO3 and MgCO3, Ca(OH)2, Mg(OH)2, Al(OH)3, Fe(OH)3 - 70.0-75.0, and the organic part comprises crude oil and its processing products, including fractions of oils, resins, asphaltenes, and their modifications - asphaltogenic acids.
EFFECT: intensification of burning process.
