Abstract: Concrete is being widely used for the construction of most of the buildings , bridges, etc throughout the world. Hence it is the backbone to the infra structure development of a nation. India is taking major initiatives to improve and develop its infrastructure by constructing express highways, power projects and industrial structures. A huge quantity of concrete is required to meet out this infrastructure development. Rice husk ash (RHA) is the byproduct of burned rice husk at higher temperature. Considerable efforts are being taken worldwide to utilize natural waste and by product as supplementary cementing materials to improve the properties of cement concrete. RHA is a product of paddy industry. Rice husk ash is a highly reactive pozzolonic material produced by controlled burning of rice husk. Hence currently the entire construction industry is in search of a suitable and effective waste product that would minimize the use of cement and reduce the construction cost. Few of such products have already been identified like Rice Husk Ash. Fly Ash (FA), and Silica Fumes etc. Rice husk ash globally approximately 600 million tons of rice paddy is produced every year. On an average 20% of the rice paddy is husk giving an annual total production of 120 million tones. From rice husk the concept of generating energy has great potential. Rice husks are one of the largest readily available but most underutilized bio mass resources being an ideal fuel for electricity generation. In recent years special attention has been devoted to industrial sectors.
