Waste disposal is rapidly becoming one of the most important technological endeavors of the authors time, and fixation of waste in cement-based materials is an important part of the endeavor. Investigations of given wastes are usually individually conducted and reported. In this study, data obtained from investigation of critical flow rates for three distinctly different wastes are correlated with apparent viscosity data via a single empirical equation. Critical flow rate, which is an important variable in waste grout work, is defined as the flow rate at which a grout must be pumped through a reference pipe to obtain turbulent flow. It is important that the grout flow be turbulent, since laminar flow allows caking on pipe walls and causes eventual plugging. The three wastes used in this study can be characterized as containing (a) high nitrate, carbonate, and sulfate; (b) high phosphate; and (c) high fluoride, ammonium, an suspended solids waste.
