abstract
An extensive laboratory and in situ investigation has been carried out aiming at studying the performance of deep mixing (column) improvement of alluvial soft soil. The laboratory research was primarily focused on the choice of an appropriate binder and dosage for the in situ application. Different binders (e.g. portland cement, composite cement, and blast furnace cement) in combination with quicklime were used. The results of a series of Unconfined Compression (UC) tests showed that blast furnace cement performs rather well in terms of strength and stiffness. The experimentation in situ consisted of instrumentation of trial embankments built both on improved and nonimproved soil. A careful inspection of the actual columns confirmed the key role of lime on homogeneity of the mixed zones and the good incorporation of cement into soil. Finally, the outcome of the monitoring of the trial embankments showed that a settlement reduction of the order of 65% can be achieved at a binder dosage of 200 kg/m3. The lowest binder dosage of 100 kg/m3 was found to be insufficient to produce considerable improvement in the soil conditions studied here.
