Effect of synthetic refractory aggregates on the hydraulic and other properties of commercial high alumina cement

摘要

Three type of refractory aggregates were synthesized from low cost materials viz. Floy ash, beach sand sillimanite and kyanite by reaction sintering with alumina and other dopants. The aggregates were characterized and castable biquettes were prepared using commercial high alumina cement as binder. Some of the hydraulic and other properties of the castable briquettes have been studied and results are Discussed in the paper.
