Cement, Calcium-Aluminate

Calcium-Aluminate cement (CAC) is a type of hydraulic cement primarily composed of calcium aluminates. It is produced by sintering or fusing a mixture of limestone and bauxite at high temperatures. CAC has excellent early strength development and high temperature resistance, making it suitable for various applications. It is commonly used in refractory concretes, where high heat resistance is required, such as in furnaces and kilns. CAC also finds use in construction materials that need rapid setting and high durability, such as rapid-setting mortars and repair products. It is chemically reactive and can undergo hydration, similar to Portland cement, resulting in the formation of calcium aluminate hydrates that contribute to the strength and performance of the cementitious system.
