Geotechnical Characteristics of Oil-Contaminated Granitic and Metasedimentary Soils
Z.A. Rahman, U. Hamzah and N. Ahmad

Abstract:
This study was designed to investigate the geotechnical properties of oil-contaminated soil for two different residual soils originally developed from in situ weathering of granitic and metasedimentary rocks. The physical characterisations of the soil were determined including particle size distribution, specific gravity test and X-Ray Diffraction (XRD). The engineering parameters for the contaminated and uncontaminated soils were Atterberg limits, compaction and soil shear strength. The amounts of hydrocarbon added to soil were varied at 0, 4, 8, 12 and 16% of dried weight of soil samples. The results from the particle size distribution analysis showed that residual soil from granitic rock comprises 38% sand, 33% silt and 4% clay while metasedimentary soil consists of 4% sand, 43% silt dan 29% clay. The mean values of specific gravity for the granitic and metasedimentary soils are 2.56 and 2.61, respectively. The types of minerals present in granitic soil sample are quartz, kaolinite and gibbsite while metasedimentary soil consists of quartz and kaolinite. The Atterberg limits value decreased as a result of increasing amount of added hydrocarbon into the soil. A similar behavior was observed with the values of maximum dry density and optimum water content with increasing hydrocarbon content. The maximum deviator stress, qmax for granitic and metasedimentary soils ranged between 6-28 kPa and 8-27 kPa, respectively. The overall unconsolidated undrained shear strength, Cu showed a decreasing trend with the increase in hydrocarbon content.
