This study mainly inspects the production of durable and environment friendly concrete by utilizing Fly Ash [FA]. This fly ash is the byproduct occurred from the coal based thermal power plants as cementitious material. High Volume Fly Ash [HVFA] Concrete is topic of discussion as it utilises FA as cement replacement to greater extent [more than 40%replacement]. Owing to their pozzolanic properties, FA is examined as partial replacement of cement with varying proportions [40%, 45% and 50%by weight] in this study as HVFA concrete. The grade of concrete adopted to observe the performance of HVFA concrete is M30 and were tested for analyzing their strengths-compressive ability, strength on the flexural capacity and their split tensile strength, after curing the molded samples 7 days, 28 days and 90 days respectively.
