Notes. Calcium Aluminate Cement (CAC) is a super refractory material. It is made by fusing or sintering alumina and calcia contributing minerals to produce monocalcium aluminate (CaAl 2 O 4) clinkers that are subsequently powderized.CAC is far superior to Portland cement in its setting properties and its ability to withstand high temperatures and chemical attack.
