Effect of Rice Husk Ash on Soil Stabilization

The soil frequently is fragile and has low stability in heavy loading. The objective of this study is to review the stabilization of soil using sustainable methods. Some strengthening approaches are available for stabilization of expansive soils. These methods consist of stabilization with soil replacement, chemical additives, moisture control, rewetting, surcharge loading, compaction control and thermal methods. The disadvantages may be associated with all these methods due to ineffectiveness and expensiveness of these methods. Based on literature, Portland cement, scrap tire, lime and fly ash and are less expensive and effective to soil stabilization.
