This paper presents the results of experimental research into the effects of lime and/or cement stabilisation on the plasticity of clayey sediments dredged from the Port of Taranto (Italy). The general aim of the research is to study the effect of artificial stabilisation on the physical properties and behaviour of this material in order to choose the best option for its re-use. After a brief description of the physical and mechanical properties of these natural sediments, their plasticity properties are compared with those of the same clays when treated with lime and/or cement, after different curing times of up to 4 years. For each stabilising agent, the effect of treatment is analysed and the experimental data are interpreted by means of a chart of plasticity paths. The chart was developed to provide a method for evaluating the effect on clay plasticity of treatment with given additives for given curing times.

Abstract

This paper presents the results of experimental research into the effects of lime and/or cement stabilisation on the plasticity of clayey sediments dredged from the Port of Taranto (Italy). The general aim of the research is to study the effect of artificial stabilisation on the physical properties and behaviour of this material in order to choose the best option for its re-use. After a brief description of the physical and mechanical properties of these natural sediments, their plasticity properties are compared with those of the same clays when treated with lime and/or cement, after different curing times of up to 4 years. For each stabilising agent, the effect of treatment is analysed and the experimental data are interpreted by means of a chart of plasticity paths. The chart was developed to provide a method for evaluating the effect on clay plasticity of treatment with given additives for given curing times.
