Geotechnical aspects of dike construction using soil-ash composites

Abstract

An analysis of using of anthropogenic materials, mainly ashes from Coal Combustion Products (CCP), for dike construction is shown. Perspectives of anthropogenic materials application in geotechnical engineering and their advantages in sense of the carbon dioxide reduction are discussed. According to regulations of Kioto Protocol 2005 and EU agreement „Energy Roadmap 2050” recycled materials have higher usage priority than natural ones. General remarks about constructions using soil-ash composites are given with discussion about their properties and laboratory investigation. Finally the full-scale experiment within the DREDGDIKES Project (www.dredgdikes.eu) is described, which is focused on the new technology with the usage of dredged and anthropogenic materials for construction of dikes.
