Overburden soil and marine dredging sludge utilization for production of new composites as highly efficient environmental management.

The main objectives of this study were to develop new composites only from industrial wastes: overburden soil (40-60 wt%), dredging sludge from marine port sediments (20-40%) and lime production waste as a binder (15-30%). The axial resistance strength of the developed materials, on the 365th day, was 18.9 MPa and the values of apparent density and dilatation coefficient ranged from 2.
