Calcium Aluminate Cement (CAC), also known as High Alumina Cement, is a hydraulic binder produced by sintering bauxite and limestone at high temperatures followed by grinding. It is characterized by high alumina content, rapid hardening, high early strength, and excellent resistance to high temperatures and chemical corrosion.
High early strength and rapid hardening
Excellent high-temperature resistance
Good resistance to sulfate and chemical corrosion
Stable hydration properties
Suitable for refractory and construction applications
