USABILITY OF ADDITIVES IN THE AMELIORATION OF ABATTOIR SOIL FOR CIVIL INFRASTRUCTURES
Abstract
Palm oil fuel ash (POFA) in both cost-effective and environmentally friendly ways has potential applications in soft soil stabilization. This study investigates the possible uses of POFA (individually and in combination with cement) on several basic characteristics of clayey soil behavior, such as proctor compaction, Atterberg limit, and unconfined compression strength (UCS). These properties are compared with those of unstabilized clay and stabilized clay with cement. Scanning electron microscopy with X-ray micro analysis is conducted on untreated and treated soil to elucidate their strength development, and the observed test results are then explained. Findings show that palm oil fuel ash treatments result in significant reductions in the soil plasticity index (PI). The results of the compaction test indicate that the utilization of palm oil fuel ash /cement mixture in soft soil stabilization decreases the optimum moisture content and increases the maximum dry density across selected binder dosages.
