High Alumina Refractory Cement (Calcium Aluminate Cement) is a specialized hydraulic binder with alumina content typically ranging from 50% to 80%. It develops rapid strength at both ambient and elevated temperatures, enabling durable bonding in refractory castables, ramming mixes, gunning materials, and repair products.
The cement provides excellent resistance to high temperatures, thermal shock, slag attack, and chemical corrosion, making it suitable for rigorous industrial environments. Its controlled setting time and strong bonding performance allow flexible usage in on-site construction, furnace maintenance, and monolithic refractory production.
High Alumina Refractory Cement is widely used as a key ingredient in high-performance refractory formulations for steelmaking, cement production, petrochemical furnaces, and various industrial kilns.
