ENHANCING THE ENGINEERING CHARACTERISTICS OF POLLUTED SEDIMENT SOLIDIFIED WITH POZZOLANIC BINDER

Since the France regulation about dredged waste sediment in respect of environmental issues has been established, the ancient method such as rejection the dredged material waste is not applicable anymore. According to previous project, the disposal site method cost very expensive. This is the main reason why the reutilization of this dredged sediment waste should be realized as soon as possible. This paper intended to identify the possibilities of the reuse of dredged polluted sediment in road construction work. The first step is to identify the characteristics (physical and chemical) of dredged sediment waste. The second step is to determine the ideal type of binders and its composition. This step is to determine the capability of binders used to improve the geotechnical performance of dredged sediment and can satisfy the requirement need in work construction work. Fly ash used in this study, is a raw waste of local coal mining. The various test were performed and the result shows that the addition of Fly ash in the mixture capable to improve the strength in geotechnical properties and confirmed that even though the content of heavy metal is very high, the stabilization process can achieve the requirement needed in work construction
