Abstract

Most of the soil available for infrastructure development is not suitable for construction. It is a real challenge to overcome the difficulties faced with the problematic soil. We need to get better of difficulties experienced with those soils. In India around The annual output of RHA is 31 million tons..It contains around 85%-90% silica which pollutes the environment and also causes health hazards.As it is producing in large amount every year, there is a need to reduce the environmental pollution with produced Rice Husk Ash(RHA). Generally properties of the RHA are similar to the properties of natural soil, we are making an attempt to mixing soil and Rice Husk Ash to it. As the RHA is a non cementitious material, in experiment has added cement to the soil. In this work, while the cement is kept at a constant amount of soil in percentage, the Rice Husk Ash is taken in various percentages like Five , Ten and fifteen percentages by the amount of the soil. The soil index traced out with soil samples were tested. The objective shows this work is the safe disposal of solid waste (RHA) on one side and increasing the stability of soil which is not suitable for construction to make it suitable.
