Effect of reclaimed bauxite on andalusite-based refractory
The results show that the standard flow behaviour open porosity and bulk density of samples containing up to 22 mass reclaimed bauxite were comparable to those of the reference castable. However high-temperature properties such as static corrosion at 1400°C and hot modulus of rupture at 1500°C indicated that there is an upper constraint

The aim of this study is to provide a scientific base for understanding the flow behavior of A R C and its influence on the formation of ceramic. For this purpose the flow behavior of a series of low ultra-low and no cement ARC compositions was analyzed. A method for measuring the viscosity of the binding system of ARC was developed.

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.
