Effect of Heat Treatment Process on the Preparation of Foamed Glass Ceramic from Red Mud and Fly Ash

Abstract:

Lightweight glass ceramic foams have been prepared from a mixture of solid wastes, namely 40 wt-% red mud and 60 wt-% fly ash. In this work, we illustrate the effects of variables in heat treatment process, including the sintering temperature and the holding time, on the quality of the foams. The reduction of sintering temperature as well as the holding time, was found to limit the coalescence and improve the apparent density and the compressive strength.
