Evaluation of Dredged Soil from Detention Basin

Several large scale reclamation projects are being underway along the coastal line in Korea. Therefore the large quantity of economical backfill material is necessary to cope with the shortage of dredged soil. In this study, the amount of volume reduction of dredged soil from detention basin was evaluated based on the laboratory tests. The percentage of soil particles in dredged organic soil is about 12.5∼21.9% by weight. The content of heavy metal and environmental effect for dredged soil itself and solidified dredged soil were analysed and the results are far below than those of environmental requirement.
