Abstract
ONE of the most general problems in technical rheology is that of relating the flow properties of solid-in-liquid suspensions to the physical properties of the separate liquid and solid phases. The Bituminous Materials Section of the Road Research Laboratory has been interested for some time in the behaviour of systems consisting of fine mineral powders dispersed to very high concentrations in tars and bitumens which are substantially Newtonian liquids of high viscosity. The problem to be solved can be stated in the form of the following question: What physical characteristics of dry powders determine the relative viscosity of powder-in-liquid dispersions over the widest possible range of concentration ? The Einstein equation and various modifications and elaborations of it for higher concentrations have not provided the answer to this question.
