| Abstract | The disposal of dredged marine soils (DMS) into the ocean or on land are unsatisfactory in managing its large quantity which indicates a high demand on new ocean and land disposal. DMS are classified as contaminated waste that contain of organic matter and heavy metals. Contaminated DMS can harm aquatic organism, animals and human. It must be disposed safely to ensure the contaminants are not released. By reusing the DMS as geomaterial or fill for reclamation works, it will minimize the impact to environment. The treatment techniques towards DMS are an essential and necessary in enhancing its engineering properties and assuring the effectiveness for a long-term solution. This paper presents a preliminary study in solidifying the Kuala Perlis DMS (3.4 LL) with lowest dosage of cement (1 – 10 %) at different curing period (3, 7, 14 and 28 days). It shows the undrained shear strength (cu) value of cement-solidified were increased compare to the raw DMS. The results for cement dosage above 7 % shows a good improvement in cu value and the strength development were found increased after 3 days of curing. It was explained that the lowest water-cement (w/c) ratio tend to have a higher cu value of the cement-solidified DMS. |
