Abstract

Marine clay has contributed many problems due to the reaction and behavior of the soil according to the different conditions for instances dry and wet period. Stabilisation of marine clay is studied by chemically using rice husk ash (RHA) as the stabilizers. Investigation includes the evaluation of such properties of the soil as compaction, strength, and other engineering properties of expansive soil as well as marine clay. Upon the determination of these parameters, the optimum amount of the stabilizers and the best curing period of time and temperature are studied. The test results showed that the unconfined compressive strength (UCS) increased about 75% after 7 days. However, the results indicated that if the curing period is less than 7 days, the UCS value of the RHA treated samples are higher than those of natural samples. This suggests that the pozzolans reaction between the clay soils and RHA had achieved optimum stabilisation at 8% ofRHA content and 7 days curing time.
