Cement treating technique was developed for stabilizing soft clay as deep cement mixing method, however, the technique with dredged soil and low quantity of cement has begun to be utilized to construct a slope of seawall structure. For example, cement treated dredged soil was utilized to the intermediate buffer layer between double layered impermeable sheets of a waste reclamation landfill in Tachibana Bay, Tokushima, Japan. Since the waste reclamation site is constructed on a clay deposit with low permeability, very large settlement and deformation may occur during and after waste reclamation, thus the cement treated soil layer is required to be very high deformability. Additionally, in a case of using dredged soil of extremely high water content mixed with low quantity of cement, a large amount of shrinkage by drying is generally anticipated. In this study, a series of laboratory tests was carried out to investigate the mechanical properties of the cement treated dredged soil. Also, investigation on the procedure of desiccation and crack formation for soil stabi
lization with low quantity of cement was carried out with some cases of the installation and curing process environments.
