Product Details
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.
The cement is packed in 25kg bags, Ton bags outside as your
requirement.
