Factors Affecting High Alumina Cement Price
Composition of High Alumina Cement
High alumina refractory cement is a kind of refractory mainly composed of Calcium aluminates compound. It is manufactured by heating a mixture of limestone and bauxite to a high temperature, which results in the formation of calcium aluminate clinker. The higher the aluminum content in high alumina refractory cement, the higher its price will be.
In addition to these calcium aluminates compounds, the cement may also contain a small amount of other mineral components, such as silicate and ferrite. These components can affect the performance of cement, such as setting time and strength development. And the amount of these ingredients added also affects its price.

CA70 is a type of high alumina refractory cement with an alumina content of around 70%. This refractory cement has higher ultimate strength and better durability than CA50, but its early strength development is slower. It is commonly used in applications where high strength and durability are required, such as in the construction of precast concrete elements and in refractory applications.
