High Alumina Cement

 

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. Our high alumina cement is widely used for the production of high quality refractory castables and other special materials. It is made from bauxite and limestone with high temperature fusion process.

Characteristics:

- High alumina cement has low pH

- It has high refractoriness

- It has high durability in sulfuric acid

- It hardens rapidly

- It is less reactant than alumina or hydraulic lime

- It acts as a bonding material when added in refractory castables because it forms ceramic bond at high temperatures

- It has high resistance to chemical corrosion. So, it is widely used also in construction of water pipes, sewage pipes, factory drains, coastal constructions and in factory chimneys.

 

We offer mainly two types of high alumina cement as detailed here:
