Abstract
IT is well known that finely divided, flocculated, aqueous suspensions of clay behave as Bingham fluids at concentrations less than about 25 per cent by volume. That is, their equation of flow is : S = S o + ηD where S = shear stress applied, S o = minimum shear stress which will cause shearing, D = rate of deformation of the suspension, η = plastic viscosity.
