The rheological behavior of fly ash slurry at any concentration has a marked dependence on particle size distribution. Five groups of fly ash samples having different particle size distribution are prepared by wet sieving to simulate the fly ash collected from different fields of electrostatic precipitator hoppers. Six suspensions of different solid concentrations (by weight) are prepared from each sample to study the effect of solid concentration on the rheological parameters. The study shows that the fly ash slurries above a solid concentration of 40 % by weight are non-Newtonian and that the experimental data fit a simple Bingham plastic model. It further shows that the rheological parameters increase monoton-ically with the solid concentration and have higher values for finer particulate suspensions.
