The aluminate cement can resist a high temperature at which a relative high strength still remains its refractoriness increases with the content of CaO, therefore it is suitable for making refractory castables as a Bonder. Depending on the refractory aggregates (fireclay, high alumina)used, the refractory Castables made of the cement can be used below 1400℃.
