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.
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.
