Product Description

High Alumina Cement Introduce

Calcium aluminate cement/aluminate cement/high alumina cement are collectively referred to as refractory cement. High alumina cement (formerly known as bauxite cement) is a hydraulic cementing material made of high-purity calcium materials and high-purity alumina as the main raw materials, and clinker with alumina content of about 50%.According to the different content of Al2O3,they can have totally foue types:CA50,CA60,CA70 and CA80.

CA-50, CA-70, CA-80, the alumina content is greater than 48%, 68% and 77% respectively. Its refractoriness is greater than 1650°C. The use temperature can reach 1800ºC, and the impurity content is lower than other common cements.

Advantages of High Alumina Cement

1.High refractoriness, up to 1650ºC±50ºC;
2.High density, low porosity.
3.High strength and wear resistance.
4.Good thermal exfoliation.
5.Good resistance to slag invasion;
6.Good plasticity and convenient construction;
7.High bonding strength
8.Good thermal shock stability.
