Abstract

Clay is a soil with poor characteristics, which include low weight bearing capacity hence it needs to be fixed. Stabilization is a soil improvement technique, involving the use of cement for increase bearing capacity. However the high cost of cement, led to the investigation of other alternatives, e.g. Rice husk ash (RHA), a pozzolanic agricultural waste, which contains a lot of silica, processed by burning husk ash. This study therefore analyses the effect of substituting RHA on the physical and mechanical property of clay, in an attempt to increase the value of its carrying capacity. Laboratory scale testing was based on ASTM standards, which include California Bearing Ratio (CBR) and Unconfined Compression Test (UCT). The variation of RHA applied to the sample were 3%, 6%, 9%, 12% and 15% of the soil (dry density), at a curing period of 0, 3 and 7 days. The results further showed that the optimum value of UCT (1.05 kg / cm²), was obtained at 6% RHA, within a 7-day curing period. The optimum CBR value (13.12%) was obtained with the unsoaked mixture at 9%, with a 7-day curing period.
