| Abstract: | Weak marine clay deposits exist all along the seacost of many parts of the world. Due to the poor engineering characteristics of these deposits, they pose several foundation problems to various coastal structures. Because of the high salt content in these deposits, the electro-osmotic technique has been effectively adopted to stabilize these deposits with some inorganic additives. In this investigation, the physico-chemical changes that occurred in a marine clay with various inorganic additives are presented and discussed. The improvement in the strength and plasticity characteristics of the soil have also been studied and reported. The newly formed reaction products arising out of the diffusion of lime are identified using X-ray diffraction technique (XRD). The present study indicates great promise regarding the use of electro-osmotic technique with inorganic additives as a quick remedial measure for the in-situ stabilization of coastal marine clay deposits. |
