Abstract

The paper reports on a study involving three series of chemical stabilization tests in successive stages. One hundred and fourteen flocculation-sedimentation tests were performed to evaluate the effectiveness of 22 different chemical additives in accelerating the sedimentation of five different fresh-water dredged materials. The findings of the flocculation-sedimentation tests formed the background for a series of 26 flocculation-sedimentation-leaching tests involving five chemical additives and two different dredged materials to assess the effectiveness of chemical stabilization in terms of shear strength, deformability, permeability, and density of the dredged materials and pollution potential of the leachates. Finally, 22 repeated leaching tests were conducted to determine the effectiveness of lime on the long-term physical characteristics of the sediments and leachates associated with seven different dredged materials from five different harbors.
