Rheological behavior of bentonite suspensions

The objective of this research is to investigate the concentration effect o n the rheological properties of different bentonite suspensions. Experiment s were performed with different bentonite type and concentrations and the r esults were evaluated by different rheological models (Bingham plastic, Pow er law, Sisco, Casson, Herchel Bulkley and Robertson Stiff) describing the flow of non-Newtonian fluids by mathematical equations in terms of shear ra te and shear stress.
