Abstract
This paper describes the geotechnical properties of highly-moistured wastes discharged from several plants, and also describes a new method for the rapid dehydration by which the wastes become easy for the geotechnical processing. The samples tested are red muds, white muds, and sludges from a filtration plant. Consolidative and shear characteristics of these wastes are comparably discussed with those of clays and high organic soils. For the rapid dehydration, a bottom drainage method is examined at field using a polymer grid container of 5m diameter and 1m depth with the filter fabric at inside wall and bottom. Field test results prove the bottom drainage method to be very effective for the rapid dehydration of the highly-moistured wastes.
