RESUMO

Present study reports the rheological characteristics of slurries of mixture of fly ash and bottom ash slurry at high concentrations (above Cw ≈ 60 % by weight) with and without additive. The ratio of fly ash and bottom ash is kept at 4:1. Mixture of Sodium Carbonate and Henko detergent has been used as the additive. Rheological tests on slurries (with and without additive) were carried out in a Weissenberg Rheogoniometer with concentric cylinder platens. The variation of shear stress τ with shear rate γ shows that the mixture of fly ash and bottom ash slurries above a solid concentration of 40 % by weight show non-Newtonian behavior and that the experimental data fits a simple Bingham plastic model. Addition of additive results in a significant decrease in the yield stress and Bingham viscosity at all concentrations tested.
