Effects of the use of fly ash as a binder on the mechanical behaviour of treated dredged sediments

Abstract : The objective of this work was to evaluate the suitability of dredged sediments treated with pozzolanic binders as a pavement base material, and to assess the usefulness of fly ash as a soil mixture/binder with the aim of improving the engineering properties of the stabilized dredged sediments in order to make them capable of taking more load from the foundation structures. Comparing the results with other binders currently used in road construction, the addition of fly ash shows significant positive advantages. The present study covers the characterization of the dredged sediments and fly ash, compaction behaviour, pH measurement, effect on unconfined compressive strength, and the effect of cyclic wet-dry and freeze-thaw tests.
