Abstract
Cement treating technique like deep cement mixing method was generally used for stabilizing soft ground, however, dredged soil treated with low quantity of cement has begun to be utilized to construct a slope of seawall structure. For example, in Japan, a cement treated dredged soil was utilized to the intermediate buffer layer between the double layered impermeable sheets of a waste reclamation landfill. Since the waste reclamation site is usually constructed on a clay deposit with low permeability, very large settlement and deformation may occur during and after the waste reclamation, thus the cement treated soil layer is required to have high deformability. In this study, a series of laboratory tests was carried out to investigate the mechanical properties of the cement treated dredged soil.
