Abstract
The ground solidification method, which mixes an improvement material such as cement into soft ground, is one of soil improvement technologies. This method has been widely used to improve the bearing capacity and control settlement of the foundation ground. However, there is not much research on the strength recovery characteristics of cement-treated soil that has already damaged during the curing period by external forces such as earthquakes and landslides. In this paper, the recovery characteristics of the shear strength for cement-treated Kawasaki and Kaolin clays were clarified by means of a series of box shear tests and powder X-ray diffraction analysis. As a result, the shear strength recovery depends on the soil type of base material, GGBS content, and the vertical pressure for the box shear test. Cement-treated Kawasaki clay shows a strong shear strength recovery as the range from 7.4 % to 340.8 %.
