Comparative Study in Fly Ash, Glass Powder and Recycled Concrete Aggregates as a Partial Replacement of Materials in Conventional Concrete

During recent years, the consciousness regarding environmental atrocity has increased as a result the interest of the construction community in using waste or recycled materials in concrete has also aggravated. If we see around us, we can see so many materials we consider waste which rather must be opportunities. The fly ash is produced in abundance in the thermal power plants as abate product which is not easy to be disposed of and is dangerous to the environment. Recycled aggregate can be used for many purposes. To address the environmental effects associated with cement manufacturing, it is crucial to advance alternative binders to compose concrete. If a few waste materials found convenient and economic for concrete manufacturing, a major gain will be achieved in the disposal of waste management and depression in construction cost. The work audits the feasibility of fly ash, glass powder, and demolished concrete as a partial substitute of cement and natural coarse aggregate, respectively. For this intent, the procedure is partitioned into two stages. In first stage replacing 25% cement content with different proportions of fly ash and glass powder. Further tested for compressive and flexural strength, at 7 days, 14 days & 28 days and correlated with conventional concrete.
