  • Andalusite-based raw materials for refractory castable

     ·  bauxite based LC castables. A typical LCC (low cement castable) recipe (Tab 3) was used for a comparative study on refractory aggregates. The particle size distributions of the castables were calculated to fit a Dinger–Funk model with n-value equal to 0.21. Maximum grain size was fixed at 5mm and minimum at 0.1µm.
