The influence of the cenosprehes addition on the heat-resistant lightweight ceramics

Abstract
The investigating results are given for the cenosphere (the coal combustion wastes) influence on the alumina cement hydration and on the exothermic reaction parameters. It was established that the cenosphere content's increasing inhibits the cement hydration, decreases the samples density to 40 % after sintering at1200 °C, as well as it reduces the strength to 60 %, and the shrinkage to 95 % comparing to the reference samples. Judging by the strength to density ratio the optimum quantity of cenospheres in the alumina cement composition is 5‒10 %.Ill.7. Ref. 19. Tab. 2.
