  • Characterization of dredged sea mud from the Port of Koper and its potential for applications in civil engineering - preliminary results
    Mladenovič, Ana ...
    The Port of Koper, as one of the biggest and the most important ports in the Northern Adriatic Sea, constantly faces problems caused by the accumulation ofmarine sediments inside different parts of ... the port, which result in disturbances in some of the Portʼs crucial operational properties. A total of 0.45 million m3 of sediment have to be removed annually. This sediment is a mixture of clay and silt (the term ŽmudŽ is used in the following text), whichis anthropogenically polluted by certain heavy metals and chlorides, and thus represents a kind of waste for which there is insufficient disposal spacealong the Slovenian coast. According to the well-known slogan ŽNo waste here, just resources!Ž this sediment can be viewed as a potential raw material, particularly in the field of civil engineering, mainly for two reasons: in this field it is possible to use large quantities of sediments, and it is also possible, by means of different remediation processes, to permanently immobilize the hazardous substances in various types of composites(1). In order to define the best way in which to use this sediment in civil engineering applications, an extensive research project is under way.This project focuses on: (i) the accumulation of mud as a consequence of local geological processes, (ii) the chemical, mineralogical and mechanical-physical properties of the mud, (iii) the degree and type of pollution, especially with regard to the content of biologically easily accessible pollutants (2), and (iv) possibilities for the environmentally safeand technologically functional implementation of sediments into construction products and structures in accordance with the principles of a sustainable building and civil engineering industry (3, 4). The preliminary results are presented and discussed in the paper. The results were obtained within the scope of the ARRS project ŽSediments in aquatic environments: theirgeochemical and mineralogical characterization, remediation, and use as secondary raw materialsŽ, 2011-1014.
