All the infrastructure projects such as buildings, railways, water reservoirs etc. require earth materials in a large quantity. In urban areas most of the soil are of highly plastic and expanse which is not suitable for all purpose. Many times we need to haul the suitable soil from a large distance which is not economical. The behavior of soil varies with different agencies like water, temperature, and region of soil, other atmospheric agencies, and mixed surplus material also. In this project we will be tried to established important properties of soil by using fly ash which is an industrial waste material, Fly ash causes various environmental problems like groundwater contaminants. So utilizing fly ash in soil stabilization can minimize such environmental hazards. In this project we will perform direct shear test, California bearing ratio (CBR) test, unconfined compression test and proctor compaction test. For this project we selected Black cotton soil which is available in Near Mantralaya, Naya Raipur (Chhattisgarh) India, region. We followed all the procedure prescribed in IS 2720 Part 7, 10, 16, and 40. Fly ash is often wont to stabilization bases or sub grade to stabilize back fill to scale back lateral earth pressure and to stabilize embankments to boost slope stability. Typical stabilized soil depths are 15 to 46 cm. the first reason ash is employed in soil stabilization applications is to boost the compressive and cutting strength of soils. The compressive strength of ash treated soils relies on-(i) in situ soil properties; (ii) Delay time; (iii) Moisture content at time of compaction; (iv) fly ash addition magnitude relation.
