High Strength Hydraulic Calcium Aluminate Cements In Construction
Concrete
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.
