Abstract:

Large-scale land reclamation projects have been carrying out for the past decades. Aside from the availability of the landfill materials which normally use sands or hill-cut materials, dredged materials can be used for the land reclamation. Utilizing the dredged or excavated marine clay for land reclamation becomes more popular. This paper discusses the stabilization of Vizhinjam dredged marine soil using lime and fly ash with different concentrations. A laboratory study was conducted on dredged soil treated with lime and flyash. The additives were added in different concentrationsso as to identify optimum dosage. From various tests, it was observed that with the addition of lime, the UCS value has increased by about 2.38 times the initial value and with the addition of flyash, the UCS value has increased by about 1.05 times the initial value.d.
