Oreworld Special Cements

CSA cement is a special cement with high strength, rapid setting time and low shrinkage. The main minerals of CSA cement is dicalcium silicate (C2S) and calcium sulfoaluminate (C4A3S). It is widely used to chemical construction materials such as dry-mix mortars, shot concrete, concrete repair and etc.

Special cements are cements that serve some specific function such as altering the setting or hardening behavior of a concrete, producing different colors for architectural effects, imparting superior workability, imparting water retention and plasticity to mortars, resisting the penetration of water in walls or containment vessels or simply reducing the cost of the cementing agent. This article gives descriptions of the basic characteristics of certain special cements and acid activated clay.

CSA Binder

CSA cement is a special engineering cement. Its main characters are high strength, rapid setting time, and low shrinkage. It is widely used to produce cement-based dry mix mortar.

CSA Expansive Additive

CSA expansive additive is a shrinkage-reducing high-performance additive made with calcium sulfoaluminate. It is widely used in mortar concrete.

Calcium Aluminate Products

Calcium Aluminate Cement is also called high alumina cement and refractory cement. It is mainly used to produce self-leveling mortars due to its good fluidity, fast setting time, and high strength.
