Effect of pollutants on the physical and engineering behavior of lime-treated marine clay

Rapid industrial growth and increasing population has resulted in the disch arge of wastes into the ocean, wastes which ultimately reach the seabed and contaminate the marine sediments. The soil-contaminants interaction, and t heir associated physico chemical properties with sediments control the beha vior of marine clays. Marine clay deposits of low strength and high compres sibility are located in many coastal and offshore areas. There are several foundation problems encountered in these weak marine clays, in this study, experimental work was carried out in the laboratory to stabilize soft marin e clays using the lime column technique. Also the lime-induced effects on t he physical and engineering behavior of marine clays in sulfate-contaminate d marine environment was investigated Consolidation tests indicate that com pressibility of the lime-treated samples was reduced to 1/2-1/3 of the virg in soil after 45 days treatment. The test results also suggest that the lim e column technique can be conveniently used to improve the behavior of cont aminated marine clay deposits.
