Characteristics of Dredged Sludges by Desiccation

To examine the possible reuse of dredged sludge in view of construction material, physico-chemical properties and geotechnical characteristics of desiccated sludge are investigated through laboratory experiments. The consistency test, the pH test, the XRF test and the X-ray diffraction analysis are carried out for physico-chemical proteries, and the conolidation test and the permeability test are made for geotechnical characteristics. It is concluded that the history of desiccation changes the consistency of sludge and affects its permeability and consolidation bahavior
