Proposal for mixture design of extremely low strength cement treated dredged soils with using strength development controlling agents

一般而言，水泥土表现出比天然土更高的强度和刚度。由于这一特性，水泥土表现出与裂缝发生相关的脆性行为。这一事实限制了水泥土的应用领域。在本研究中，为了抑制水泥土的强度发展，以获得可变形的水泥土，本研究重点研究了特定的助剂。试图阐明这些助剂对强度发展的影响及其机理。基于这些发现，本研究提出了使用强度发展控制剂进行极低强度水泥稳定吹填土的配合比设计。

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
