Alumina cement is a cementitious material made from alumina, calcium oxide and calcium sulfate. It is used in various applications such as refractories, masonry, and ceramic products.

Alumina cement is primarily used in refractories, where it provides a good bond between the bricks and helps to reduce heat loss. The high alumina content gives it a high refractory temperature and properties such as chemical resistance and good thermal shock resistance. It also stands up to thermal cycling, which makes it an ideal choice for use in furnaces and other high-temperature applications.

In masonry applications, alumina cement is used as a mortar between bricks or stone blocks. It has good adhesive and cohesive properties and can provide a stronger bond than regular cement or even mortar.

Alumina cement is also used for the manufacture of ceramic products. This type of cement is used for glazing ceramic products, as it helps to reduce water absorption and improve the overall strength of the ceramic product. It can also be used as a binder for the manufacture of ceramic fibers, which are lightweight and have high thermal-shock resistance.

Alumina cement is a useful material for various applications that require heat resistance, physical strength, and excellent adhesion properties. Its properties make it an ideal choice for refractories, masonry, and ceramic products.
