EXPERIMENTAL STUDY ON ENGINEERING PROPERTIES OF A DREDGED SEDIMENT SOLIDIFIED BY COMMON CEMENTITIOUS MATERIALS
This paper presents an orthogonal experimental program for investigating the effectiveness of using common cementitious materials for solidification of a soft dredged sediment. Three kinds of solidification additives including Portland cement, fly ash and lime were chosen for the experimental study. The water content and mechanical properties of the solidified sediment were measured, and the influence of each solidification additive on the solidification was analyzed. The experimental results revealed that fly ash was the most cost-effective to reduce free water in the sediment, and increase the strength and elastic modulus. It was found that both the strength and water resistance of solidified sediment were enhanced. The experimental results provide an implication to the selection of cost-effective solidification additive for the reuse of the dredged sediment in civil engineering.
