Abstract

The compressibility of clay has been expressed e-log p' graph. In natural clay, e-log p' graph are changed by deposition condition and chemical cementation as well as Atterberg limits, whereas in reconstituted clay, it is generally known that e-log p’ curve is varied with Atterberg limits. However, e-log p' graph is possible to change according to the reconstituting methods and test conditions. In this study, consolidation tests are performed as various test condition for reconstituted Busan clay. Test results show that the relationship e/$e_L$ and log p' is almost constant with $e_L$. And the compression index obtained from slurry method sample is larger than one obtained from kneading method sample. Intrinsic compression line (ICL) of Busan clay is identical with ICL suggested by Burland.
