Abstract

The article provides a basic understanding of the impact of the matrix components on the rheology of castables with special focus on high performance alumina and spinel castables. A broad particle size distribution of the matrix fines helps to achieve optimised packing and therefore a high solids content with low viscosity of the suspension. As solids content increases the amount of water is consequently reduced. Additives are required to counterbalance agglomeration of the particles in a suspension.
