In general, reclamation with dredged soils requires a lot of time and cost. Few methods have been proposed to save these two factors. Using coal ash which is a co-product of thermal power generation has brought a great attention to researchers and engineers. Field tests were conducted and the results were analyzed to figure out the applicability of an artificial soil mixture with coal ash as a reclamation material. The ground composed of dredged soils and coal ash has a similar particle distribution to sand, and more cohesive and internal frictional angle than that with dredged soil only. In addition, the coefficients of horizontal consolidation and permeability were improved as well, which means the consolidation of the mixed ground could be accelerated.
