Product Introduction
Calcium aluminate cement is cement with calcium monoaluminate or calcium dialuminate as the main mineral component. It is made by mixing bauxite or industrial alumina with calcium carbonate (limestone) and then calcining or fusing.
Features
1.Fast hardening. 2.High strength. 3.Fire resistance and sulfate corrosion resistance.
Application
Calcium aluminate cement is mainly used as a binder for refractory castables and refractory injection materials.
