Influence of destructuration by swelling and disintegration on consolidation of clay lumps
Dredged clays are commonly used in land reclamation works. These clays are excavated as lumps varying in size from few tens of millimeters to a meter. When the lumps are dumped, they are made to merge due to consolidation. But before that, the lumps invariably swell and start to disintegrate if sufficient time between the dumping of the lumps in water and the application of surcharge is permitted. The magnitude of swelling and disintegration of the clay lump would indirectly affect the magnitude of the applied surcharge needed to merge the lumps. This paper investigates the effect of size, strength and saturation on swelling and disintegration of the clay lumps submerged in water. The loss in lump's weight was the measure of disintegration. Small lumps with large specific surface area, disintegrated at a faster rate. Likewise, unsaturated lumps were also noted to swell and disintegrate quickly. On the other hand, the lumps with water content close to their liquid limit were least likely to disintegrate.
