High Alumina Refractory Cement (HAC) is a fast-setting, heat-resistant cement made from calcium aluminates, typically with ~50% alumina. It offers excellent strength, thermal stability (up to 1000°C), and chemical resistance. Commonly used in furnaces, kilns, and emergency repairs in high-temperature or corrosive environments.
Alumina cement is an inorganic material that form a dense texture when it reacts with water. It has excellent refractoriness & quick hardening and resistance to chemical attacks. These high alumina cement are used in production of high quality refractory castables & other special materials.
