Abstract: In this report, static compaction is used to determine the optimum water content and dry density for samples containing sand and bentonite. The percentage of bentonite in the mixture is varied to analyze whether the amount of bentonite in the mixture will affect the optimum water content. The initial matric suction for the samples is also conducted using the null type axis translation method.
The general observation for the static compaction process is that the optimum dry density for a given sample can be obtained by plotting the energy required for compaction against water content. It can be observed that energy required for compaction is relatively higher for samples having higher dry density. The percentage of bentonite in the sample also influences the energy for compaction. As for the initial matric suction, it is observed that there is a trend of decreasing matric suction with increasing water content. Also, mixture content of the sample and the initial dry density influences the values of the initial matric suction.
