| Abstract | A preliminary investigation of sludge rheology was carried out on two tailings pond sludge samples; a low bitumen content (1%) and a high bitumen content (3-4%) sample. Steady state shear stress versus shear rate measurements and dynamic measurements were performed. Quanlitativ8 measurements of structure buildup and breakdown as a .function of time were obtained. Strain sweep analysis on sludge samples was determined and Ihe linear Viscoelastic region was defined (the region where the sludge structure has not been broken). Viscoelastic properties of the sludge in the linear yiscoelastic region were characterized. Preliminary investigation of high bitumen content sludge indicated that varying amounts of bitumen are present within the sample. Therefore, it is possible to misinterpret bitumen peaks in shear stress versus shear rate plots as significant stress overshoot or yield points. A general overview or the rheological properties of sludge will be presented. |
