The progressive transition from the non-remoulded behaviour (natural soil) to remoulded behaviour is here investigated. Tests were performed on a deepwater clay sediments from the Gulf of Guinea characterized by a very high liquid limit. The results are analysed and compared on one hand with the reference behaviour of remoulded normally consolidated mineral clays established by BIAREZ and FAVRE [1], and on the other hand with intrinsic compression (ICL) curve proposed by BURLAND [4]. The study is supplemented with a local approach of microstructural analysis, using mercury porosimetry method.
