Conventional Castables
A Conventional Castable is a mixture of Alumino Silicate materials aggregates & Calcium Aluminate Cement. The Water required during application is usually 12-20%. Combination of Water and Cement forms Calcium Aluminate Hydrates resulting hardening of Castable which gives sufficient mechanical strength at Low and Intermediate temperature.
