Abstract:

Large amount of sediments are dredged from harbours and seaports for construction of the marine structures and for maintenance of the shipping channels. The dredged soil requires large area for disposal. Offshore dumping causes disruption in the aquatic environment. This soil cannot be used directlyin construction processes directly since it exhibits properties such as low shear strength, high natural water content and high compressibility. Attempts were made to stabilize the soil for embankment construction and for landfill. This paper describes the suitability of dredged soil from Akkulam in pavement construction by stabilising it with flyash based geopolymer.
