Abstract

At present days infrastructure is the backbone of the country. Infrastructure can be developed by several ways such as steel structure, concrete structure, and wooden structure. Among these structure, wooden structure are not used widely, because rapid use of wood leads to cause deforestation. Steel structures are economic and efficient in case of high rise buildings but in case of small structure it is little costlier than concrete. Therefore, concrete structure are mostly used for such type of buildings. Generally concrete compose of cement, coarse aggregate, fine aggregate and water. Nowadays concrete is used widely. It may cause scarcity of certain materials like fine aggregate. So, our main aim of the project is, to overcome the scarcity of the fine aggregate by reducing the usage. This have been achieved by replacing the rice husk based precipitated silica in the concrete at various proportion mixes (0%, 10%, 20%, 30%, 40%, 50%, 60%, 70% and 80%)replacement
