The concept of partial replacement of cement with fly ash can accomplish sustainable development. Presently large amounts of fly ash are generated in thermal industries which are dumped as waste, have an adverse impact on environment and humans. This fly ash in the powdered form can be used in concrete to replace cement. The utilization of by-products as the partial replacement of cement has important economic, environmental and technical benefits such as the reduced amount of waste materials, cleaner environment, reduced energy requirement, durable service performance during service life and cost effective structures. The objective of the paper is to evaluate a building in terms of cost and durability, by doing partial replacing of cement with fly ash. Firstly, the intensive literature survey is conducted from which it is understood that 25% partial replacement of cement with fly ask is suitable for M30 concrete. The quantity and cost estimate of a G+5 residential building is carried out which uses concrete without fly ash. Then the quantity and cost estimate is done for the same building by using fly ash concrete (concrete in which 25% of cement is replaced by fly ash). A comparative study is carried out in terms of cost is carried out between the two to understand the best economic structure.
