... rights reserved 2015 dredging geotechnical engineering strength and testing of materials Large volumes of very high moisture content fine-grained soils (e.g. contaminated sediments, mine tailings, dredged soils) are encountered and must be managed in an environmentally sound manner...

...Jorma Havukainen, MSc, CEng; Ari Piispanen, MSc; Mikko Leppänen, MSc, CEng In the new Vuosaari harbour in Helsinki, an area of 75 ha tributyltin-contaminated sediment was dredged by accurate techniques and mass-stabilised in lagoons with cement. The task was completed in December 2006. The quality...

This paper summarises a 10 year follow-up study...

... treatment on the compressibility and velocity of sedimentation and consolidation. The improvement of these geotechnical characteristics may lead to the storage of a greater volume of dredged material in the confined disposal facilities. Tests in a sedimentation column were performed in salt water...
