Abstract
Object of this work is to analyse experimentally the rheological behavior of the consolidated suspension layer. The experiment has started when the consolidated particle bed expanded visco-elastically after loading on the bed was reduced. To confirm the visco-elastic expansion of the suspension, and uniaxial compression test (UCT) was applied for a highly filled suspension (HFS) at a constant concentration of the same material as the consolidation experiment. Stress hardening was observed after loading on the UCT. A three-element model (Voigt model plus an elastic element) was found to be simple and sufficient to represent the response of the creep test after stress hardening was achieved. The expansion experiment of the consolidated HFS bed showed that real expansion appeared after loading on the bed was reduced to some limited one, FB, from the original load, FA. It was confirmed from the experiment that the load difference (FA-FB) corresponded to the friction between the cylinder wall and HFS. The visco-elastic expansion of the HFS bed on the load region less than FB showed the strain approached the predicted strain curve from the UCT experiment.
