Product Description
CA -65 High Alumina Cement For Making Castables And Alumina Products
Specification:
Calcium aluminate cements are cements consisting predominantly of hydraulic calcium aluminates. Alternative names are "aluminous cement", "high-alumina cement" and "Ciment fondu" in French. They are used in a number of small-scale, specialized applications.

Applications:
- In construction concretes, rapid strength development is achieved, even at low temperatures.
- In construction concretes, high chemical resistance is possible.
- In refractory concretes, strength is maintained at high temperatures.
- As a component in blended cement formulations, various properties such as ultra-rapid strength development and controlled expansion can be obtained.
Packaging & Shipping
The cement is packed in 25kg bags, Ton bags outside as your requirement.
