Lime treatment for the reuse of dredged marine Sediments

Abstract

An experimental research has recently been performed for developing an original sediment management and reuse procedure, consisting in the following operations: dredging of the sediments from the seabed, pumping of the dredged soil to the shoreline, reduction of water content by desiccation, addition of lime for stabilisation, placement in the embankment. In the paper some results of the experimental laboratory work carried out to highlight the effectiveness of the procedure have been reported. The suitability of lime treatment has been investigated with particular reference to the high initial water content of the soil. The efficiency of the improvement has been investigated by mechanical testing after short term since lime addition.
