Initial Stage Hardening Characteristics of Marine Clay Improved Cement

Source

Laboratory vane shear strength tests were conducted in order to study the various characteristics of the initial hardening stages of treated soils, such as the influence of moderate heat portland cement (MP) and blast-furnace slag (slag) mixture ratios, regional differences in marine clays, the influence of the quantity of additive to the slow hardening cement, and the influence of the water/cement ratio, and so forth, with respect to slow hardening cement, which is considered suitable for operations by the deep mixing method of soil stabilization in Japan. The results were that when the quantity of MP in the mixture is decreased, the shear strength of the treated soil decreases. The progress of hardening is closely related to the reactivity of the clay. The influence of the quantity of additives appears after hardening has progressed to a certain extent. When the water/cement ratio is increased, the shear strength decreases. Such characteristics were made clear, and it also became clear that the vane shear strength test is the most suitable method for studying these initial stage hardening characteristics.
