High Alumina Cement (formerly known as bauxite cement) is a hydraulic cementing material produced by grinding clinker with an alumina content of approximately 50%, in which calcium aluminate is the principal constituent. It is also referred to as refractory cement and serves as a key binder for producing low-cement high-alumina castables.
