We study the viscoelastic solid properties of cohesive particulate suspensions using creep and constant rate tests in a vane-in-large-cup geometry. A cup-to-vane diameter ratio larger than 4 is used to ensure that wall effects are minimized. In both

Several methods for measuring the compressive strength of strong particulate gels are available, including the centrifuge method, whereby the strength as a function of volume-fraction is obtained parametrically from the dependence of equilibrium sedi

The behaviour in simple shear of two concentrated and strongly cohesive mineral suspensions showing highly non-monotonic flow curves is described. Two rheometric test modes were employed, controlled stress and controlled shear-rate. In controlled str

An experimental system has been found recently, a set of coagulated CaCO3 suspensions, which shows very variable yield behaviour depending upon how it is tested and, specifically, at what rate it is sheared. At Peclet numbers (Pe)>1 it behaves as a s

The batch settling test is widely used to estimate the compressive rheology of strongly flocculated colloidal suspensions, in particular the compressive yield strength and hydraulic permeability. Recently it has been discovered (Lester et al., 2014)

Measuring yielding in cohesive suspensions is often hampered by slip at measurement surfaces. This paper presents creep data for strongly flocculated suspensions obtained using vane-in-cup tools with differing cup-to-vane diameter ratios. The three s

Ag salt nanoparticles were manufactured at high concentration in water in the presence of a series of copolymers of poly(ethylene glycol) and maleic anhydride (PEG-MA). The Ostwald ripening behaviour was then examined using the PEG chain length of th

Silver nanoparticles have been synthesised at high concentration (>1 mol L−1) in water using a series of comb-graft copolymers. The copolymers were synthesised and then derivatised from methoxypoly(ethylene glycol) acrylate and maleic anhydride. Th

Wall adhesion effects during batch sedimentation of strongly flocculated colloidal gels are commonly assumed to be negligible. In this study in-situ measurements of colloidal gel rheology and solids volume fraction distribution suggest the contrary,
