Our Reactive alumina was evaluated for high alumina castable application by an independent laboratory of international repute viz ACC , CRS THANE in 1998. High alumina castables were prepared using white tabular alumina (WTA) as aggregate base and 10% RAC 95 produced by Rohini Industries. In a comparative study imported alumina was used as the 10% additive keeping all other conditions same. Results clearly show our products are comparable to best quality reactive alumina available internationally.
