A novel settling and structural build-up measurement method

A new device, consisting of a rough plate immersed in the fluid sample, was developed to enable a simpler measurement of the sedimentation and yield stress increase of non-Newtonian suspensions. Due to the deformation of the material at rest or due to changes in the solid volume concentration by sedimentation along the vertical axis, the plate apparent mass varies with time. The apparent yield stress value of a fluid and the sedimentation rate could be calculated from this measurement.
