Method for the Mixing Design and Physical Characterization of Air-Foamed Lightweight Clay Concrete: A Response to the Issue of Recycling Dredged Sediments.

From both economic and environmental points of view, the reuse of dredged sediments in the direct onsite casting of concrete represents a promising method for replacing sand. The aim of this study was to develop a cementitious material that (i) reuses the thin particles of sediments; (ii) has a low density due to the incorporation of air foam in the material; and (iii) achieves a minimum mechanical strength of 0.5 MPa for embankment applications.
