 Description of High Alumina Refractory Cement  


Products

Calcium Aluminate Cement /High Alumina Cement CA-50

Applications

1,As binders calcium aluminates cement are used in concretes and mortars for specialised applications

 for their properties of resistance to corrosion, abrasion and heat combined

with rapid hardening and the ease of controlling grading variations.
Calcium aluminate cements are also used in combination with other fine components. Hydraulic binders

 with new properties are then obtained. In this way, aluminates act as both a complex hydraulic binder and

 a mineral reagent interacting with the other components in the mix.

2,As reagents, calcium aluminates are found in non-hydraulic systems. This is the case in metallurgical treatments

 (iron and steel industry, foundry) where specific grades of calcium aluminate are used for their low-temperature

 melting properties and for trapping molten metal impurities.

 

 

Features

1,Very low mixing-water requirement

2,Very high purity

3,High product consistency

4,High cold and sintered strength

5,Very tight specifications of setting times
