| Research Abstract |
In general, cement-treated soils show higher strength and stiffness compared to natural soils. Owing to this characteristic, cement-treated soils show brittle behavior associated with the occurrence of cracks. This fact limits the fields which cement-treated soils can be applied. In this study, particular agents were focused to suppress the strength development of cement-treated soils and to obtain deformable cement-treated soils. Attempts were made to clarify the effect of the agents on the strength development and the mechanism. Based on these findings, this study proposed mixture design of extremely low-strength cement-treated dredged soils with using strength development controlling agents
