High-alumina cement, also known as calcium aluminate cement, is a special type of cement made from bauxite and limestone that are calcined to produce clinker, which is then finely ground and mixed with gypsum. It is characterized by its high alumina content, high strength, and high heat resistance, making it a crucial component in the refractory materials industry.
