Effect of Deflocculants on High Alumina Low Cement CORE
In this project the effect of different types of deflocculant and its amount on high alumina low cement castables is observed. As the flowability is dependent on the particle size distribution and packing of the castable system the particle size ranges follow a continuous distribution approach based on

The effect of deflocculants on the self-flow
· The influence of several deflocculants on the self-flow characteristics of an ultra low-cement high-alumina castable in the Al 2 O 3 –SiC–C system has been studied. The behavior of various deflocculants in high-alumina castables was evaluated in terms of apparent viscosity and pH of the matrix and self-flow value of the castable.
