Experimental study on black cotton soil treated with xanthan gum and palm oil fuel ash

This paper presents the results of laboratory evaluation black cotton soil stabilized with Palm Oil Fuel Ash(POFA) and Xanthan Gum(XG), to determine its suitability as reliable construction material. POFA, a major byproduct palm oil industry is being dumped into open fields which can cause environmental problems. Using POFA an additive in stabilization be eco-friendly sustainable practice. XG generally used thickening agent food pharmaceutical industries this study binding Several influential properties such UCS, CBR, Compaction characteristics, Atterberg limits were found for control samples compared treated different percentages ratio on curing periods. The tests are performed by varying (0-25%) while keeping constant at 1% weight dry soil. specimens cured There significant change shear strength UCS value increased 374% CBR 379% when sample those 20% POFA+1% 90-day period.
