Fines play a major role in the self flowing characteristics of castable which has been studied by using two different alumina fines, namelyWTA (white tabular alumina) fine and reactive alumina in the selfflow low cement castable with distribution coefficient, q = 0,21 and 0,23 as per Dinger and Funk particle size distribution models. The castables were processed as per normal processing and properties were compared at three different temperatures. Results showed that reactive alumina containing composition showed improved properties than that of WTA fines batch for all the temperatures.
