The main objectives of the soil stabilization are to increase the bearing capacity of the soil, weathering resistance and to enhance different properties of soil so as to make it more efficient. Unstable soils can create many problems such as in foundation and weak superstructure. Therefore it is necessary to stabilize the soil techniques to ensure the good stability and bearing capacity of soil and it can sustain more loads. According to times of India in our country 32000 million ton industrial waste is generated annually in which the ratio of fly ash and rice husk is 0.82%(265 million tons) and 0.41%(132 million tons) and out of that only 50 to 60% of these are utilized. Waste materials such Fly Ash, rice husk ash, pond ash may use to make the soil to be stable. Addition of such materials will increase the physical as well as chemical properties of the soil and also that is how we can more practically utilize these industrial wastes. Some properties which are expected to be improved are shear strength, unconfined compressive strength and bearing capacity etc. California bearing ratio (CBR) and other strength property tests were conducted on soil. By using waste material it reduces the cost of construction or we can say economical. The main problem with waste is their disposal so by using this we try to decrease their hazardous effect on environment. These materials show great results and can be useful in this sector as well also the results shows that they are not only the substitute of the conventional stabilizers but also they can be superior to them in some aspects.
