Calcium aluminate cement is a cement with calcium mono aluminate or calcium aluminate as the main mineral component. It is made of natural bauxite or industrial alumina and calcium carbonate (limestone) in a certain proportion and is made by calcination or electric melting, and it is also made by melting bauxite and limestone.
