Purpose:This study examines the effects of distribution of particle size-dimensions on refractory properties of alumina based castable refractories in which calcium aluminate cement (Secar-71) is used in low proportions as the hydraulic binder,which affects negatively properties of a refractory at high temperatures owing to its CaO content.
