    Sammanfattning : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging activities are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. LÄS MER
