Abstract
A method is described of continuously monitoring pressure changes at various depths during the concentrated suspensions. The results show the development of interparticle reactions and transfer of load to the base and walls of the vessel which, for low specific surface suspensions, closely follow simple classical predictions. For the higher specific suspensions, characteristic of many industrial powders and pigments, the process appears to involve self consolidation of an initially poorly compacted deposit. An analysis is given which relates several different methods of approach to the continuity relations which hold during the settlement and consolidation of concentrated two-phase systems.
