INFLUENCE OF DRYING ON THE LIQUID LIMIT BEHAVIOR OF A MARINE CLAY

A marked decrease in liquid limit was noted on drying marine clay specimens fromm the south-west coast of India. This study examined the various factors responsible for the reduction in liquid limit of the Cochin marine clay on drying and a mechanism for such a reduction is proposed. Halloysite was found to be absent, and the possibility of cementitiuous material being responsible for particle aggregation and reduction in clay plasticity on drying was ruled out. It was found that the presence of calcium and magnesium as the predominant exchangeable ions and of a high pore salt concentration factiitates strong interparticle attraction and small particle separations. Conclusions drawn from these findings are discussed.
