Part 1 to a series of 2 books on the dredged marine soils of Malaysian waters, Book 1 gives an overview of dredging works and the engineering characteristics of the dredged marine soils retrieved from Malaysian waters. Besides dredging activities, a description of the materials’ physical, chemical and biological properties are included in the early chapters. Also, elaborating on the potentially effective though time-dependent thixotropic hardening of clay and silt sediments, the self-treatment of the soils could be a feasible solution to putting the dredged marine soils in reclamation works as backfills.
