Insulating Fireplace Refractory Castable High Alumina Refractory
Cement 40% - 80% Al2O3
Quick Detail:
Model Number: CA-70 CA-75 CA-80
Al2O3 Content (%): 40%~80%
Material: Alumina Cement
Description:
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:
1. In construction concretes, rapid strength development is
achieved, even at low temperatures.
2. In construction concretes, high chemical resistance is possible.
3. In refractory concretes, strength is maintained at high
temperatures.
4. As a component in blended cement formulations, various
properties such as ultra-rapid strength development and controlled
expansion can be obtained.
