Every year, large volumes of dredged marine soils (DMS) are removed from Malaysian water. Dredging activity is needed to maintain and enlarge water bodies. DMS properties are varies depending to space, time and land uses in the watershed. DMS were also reported to be contaminated with chemical and biological contaminants, making the materials risky for reuse. Information on DMS properties, e.g. physical, chemical and biological properties is essential to the selection of a suitable reuse option. This study is focused on the characterization of Malaysian DMS for beneficial reuse. Three samples from different dredging sites and one sample of sediment as a control were used in this study. Physical properties of DMS from Malaysia water were identified and quantified. The DMS were classified as high plasticity clay (CH), high plasticity silt (MH) and low plasticity silt (ML) for Lumut, Melaka and Tok Bali respectively. The results showed that the DMS from different locations have different physical properties. Thus, the characterizations of DMS with regards of physical properties are significant in decision making either to be reused or disposed.

“…Bangkok Administration Metropolitan is responsible for maintaining of the Watsongpeenong canal by dredging the sediments from the bottom of this canal. Dredged sediments with annually approximately hundred millions of tons are generated in worldwide [1], [2]. Many studies show that sediment from river can be used in the production of bricks as the natural clay replacement that comply with construction standard [3]- [10].…”

Abstract-The laboratory-scale study was conducted to assess the feasibility of using dredged sediments from Lumsai canal with rice husks to produce bricks. This study was investigated into three different proportions of dredged sediments with rice husks ranging from 0, 5, 10, 15, and 20 percent (by weight of rice husks or rice straws) as raw materials in producing bricks. The characteristics of the dredged sediments, rice husks, and fired bricks were analyzed using X-ray fluorescence (XRF) and X-ray diffraction (XRD), respectively. The physical-mechanical properties of fired bricks were found to comply with the criteria for bricks (Thai Industrial Standards 77-2545). The obtained results indicated that major chemical compositions of dredged sediments were silica (SiO 2 ) 56.27 percent, alumina (Al 2 O 3 ) 11.76 percent and iron oxide (Fe 2 O 3 ) 7.84 percent, and heavy metal contents including Cr, Cu, Zn, As, Cd, Hg, Pb, Mn, Sr, and Ni were lower than the soil quality standard. Results of this study showed that bricks made from dredged sediments with 5 percent of rice husks were suitable as primary raw materials in the production of bricks without harmfulness.Index Terms-Bricks, dredged sediments, rice husks.

“…Los estudios presentados por Newman (11) concluyeron que es poco probable que la presencia del ión de cloruro del agua salada afecte las propiedades del hormigón más allá de una leve aceleración de los tiempos de fraguado y la tasa de aumento de resistencia. Otros trabajos (17)(18)(19)(20)(21)(22) señalaban la viabilidad de usar sedimentos de dragado marino en las bases y subbases de construcciones de pavimentos portuarios. Se incorporaron en los sedimentos marinos mezclas de aglomerantes hidráulicos (cemento o cal) para mejorar su distribución granulométrica y corregir su esqueleto granular.…”

“…Studies presented by Newman (11) concluded that the presence of chloride ion from the salt water is unlikely to affect the properties of concrete beyond a mild acceleration of the setting times and rate of strength gain. Other works (17)(18)(19)(20)(21)(22) indicated the feasibility of using dredged marine sediments in the bases and sub-bases of harbor pavement constructions. Hydraulic binder mixes (cement or lime) have been incorporated into DMS in order to improve its grading distribution and correct the granular skeleton.…”
