In the southern port region of Vietnam, many deep mixing (DM) columns have been installed to increase the stability of slopes and mitigate ground settlement. Prior to DM production, laboratory mixing tests should be executed carefully. In fact, there is significant variation in cement dosage due to the required performance (UCS, criteria), soil condition and local cement property. This paper describes the clay property and considers a case study of a laboratory mixing test using the local clay deposited at major river deltas in the South of Vietnam and the Southern United States, and considers differences with Japanese clay mixing results. In addition, deformation characteristics associated with DM installation is considered based on the measured data. |
