INFLUENCE OF CERTAIN SCRAP FROM NON-FERROUS METALLURGICAL PLANTS ON THE PHYSICAL AND MECHANICAL PROPERTIES OF BRICK

摘要

It is established that addition to compositions of ceramic compounds used in brick making, of the clayey portion of "tailings" from gravity concentration of zirconium-ilmenite ores, ash from thermoelectric power plants, and final overburden coaly-day shale (the country rock of gold-ore deposits) improves the physical and mechanical properties of the brick. Regression analysis demonstrates that a sufficiently good description of the experimental data is provided by second-order linear equations.
