Use of rubber crumb in the production of building ceramic

Abstract

The prospects for using rubber crumb, obtained by processing automobile tires, in the production of building ceramic are examined. It is established on the basis of experimental data and preliminary statistical calculations that the addition of rubber crumb in amounts 5 – 10% changes the values of the physical–mechanical properties and structural indices of ceramic samples. The composition and amount of gas released during heat-treatment of ceramic samples is analyzed. It is established that additions have a negligible effect on the phase composition of ceramic samples. Rubber crumb makes it possible to obtain samples with satisfactory properties and to reclaim polymer wastes.
