Fly ash is the waste byproduct formed by the combustion of coal in furnaces. In India, the availability of fly ash is significant as India has some of the largest coal reserves in the world. Indian coal has a high ash content and a low calorific value. In India around 73% of the powerplants are thermal based and amongst them 90% are running on coal. Until ten years ago, fly ash was treated as waste all over the world, but now it has been developed as an environmental savior. Since the amount of fly ash generated through these plants are huge and they have the potential to be reused along with other building materials. Many researches are currently being done and many are already done to solve the problem and their economic usage. They offer huge cost savings and can be a sustainable alterative. This paper discusses the ongoing practices where fly ash is being used as a alternative material and their potential savings.
