Abstract
Soft marine clay deposits are present in many coastal regions of the world and they are usually enriched with chlorides and occasionally with sulphates. The use of lime to improve the properties of soft clay deposits is not new. A test program was carried out to study the changes in the particle level of soil systems attributed to lime in a marine environment. The formation of various new reaction products due to soil-lime reactions were identified by X-Ray Diffraction (XRD) and the same was investigated using Scanning Electron Microscope (SEM). The test results indicate that the presence of chlorides encourage the efficiency of lime stabilization, but the presence of monovalent sulphates affect the improvement of the soil system due to the formation of the swelling compound, etttringite. It is suggested, that the lime injection technique can be conveniently used to improve the behavior of soft marine clay deposits.
