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

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. These high alumina cement are used in production of high quality refractory castables & other special materials. It is made from Bauxite and limestone with temperature fusion process.
