Low Cement Refractory Castable adopts submircon technology. Micro powder is used as binder, aluminate cement as coagulation accelerator, some antidetotant and water reducer will also be added in during the production of low cement refractory castable, compared with common castable, they have the advantages below:
1. Dosage of cement is more lower, the content of Cao will be only 1/4-1/3 of common refractory castable. 2. Water consumption rate during the construction is almost 1/2 or 1/3 of the common refractory castable, with high density and low porosity. 3. Good volume stabilit under high tempetature. 4. High normal temp cure property, intensity will be increased after medium tempetature and high tempeature. Three or five times more than common refractory castable.
