A Comparative Study on the Stabilization of Soft Soil Using Agricultural Wastes (Baggase Ash (BA) And Rice Husk Ash (RHA)

Soft soils are expansive soils, also referred to as tropical clay. soil may cause instability foundations thereby reducing their service life, this necessitates the adoption of a suitable stabilization method in order improve engineering properties soft soils. This research work aims at comparing strength stabilized using two different agricultural wastes- Bagasse Ash (BA) and Rice Husk (RHA). The studies were conducted determine natural treated oxide composition BA RHA evaluation effect (0, 2, 4, 6, 8, 10 12 % by dry weight soil) on index soil, determination characteristics (proctor compaction , unconfined compressive (UCS), California bearing ratio, (CBR) under soaked unsoaked conditions) with mixtures, optimum blend both needed for clay comparison stabilizing agents performance soil. From test results, it was observed moisture content be 18.02%, indicating that material is relatively high water holding very low porosity specific gravities 2.66. maximum density (MDD) increased higher an lying between 8-10% MDD continuously decreased addition OMC increase, increase possible percentage increment 11.20% increases 16.2%. leads consequent CBR value 9%. obtained 10% 28.72%. UCS change 630% 91.41% respectively while increments 619.8% 85.23% recorded thus improved better although smaller addition.
