Abstract

A laboratory and centrifuge study was carried out to assess the effects of polymer treatment (PT) on the geotechnical behaviour of a low plasticity slurry, when compared to an untreated (UT) material. The study indicated that PT resulted in lower densities at a given vertical effective stress, higher rates of consolidation, increased permeability, a modified critical state line, increased undrained strength at a given density, and had negligible effect on cyclic resistance and post-cyclic strength. Centrifuge testing confirmed the lower densities and higher rates of consolidation of PT material, while giving uncertain strength results from penetrometer testing.
