RR Normal Crete Castable
RR crete super castable and RR Normal castable are scientificaly design ready mixed castable made from Recon Refractory superbond, a medium aluminate binder and selected refractory bauxite.
These refractory castable are hydraulic Setting and can be in situ cast or molded to any Shape and also mixed for guning of furrnance lining.
The water content for rodding or viberating should be 10% to 15% by weight of castable to obtain workable consistency.
