IHLEN Utilisation Refractory use About 95 of the sillimanite minerals produced are used as raw material for the refractory industry in the manufacturing of non-basic high-alumina refractories (Roskill 1990 O Dris-coll Harries-Rees 1993). The refractory characteristics of these minerals is related to their ability to form the refractory mullite
Effect of different high alumina cements on the properties
· Self flowable castables hence need to possess more amount of fines in order to be self flowable. The binding phase in cement bonded castables is high alumina cement .High alumina cement consists of mainly the phases CA CA2 and C12A7. Out of these phases C12A7 phase sets the most quickly and CA2 takes the most time to set. The greater the amount

ABSTRACT. Monolithic refractory castables bonded with calcium aluminate cements (CACs) have a rich history of nearly 90 years. They have evolved from high-cement conventional formulations to the era of reduced-cement castable systems that can be placed using a variety of techniques such as casting gunning self-flow pumping and shotcreting.

· Different binders also show different behaviors in terms of the final porosity of castables. In a related study Ismael et al. compared different binders (i.e. CAC HA CS) with refractory castables and observed that different binders provide different permeabilities . CAC and HA provide low-density products due to the hydration process and
