Abstract
Fibers are used to resist the cracks and strengthening of the concrete. In this research work, the steel fiber and fly ash were used. But the concentration of fly ash was same in all the beam specimen and different variation of steel fibers below the neutral axis were utilized. The whole process of using different material above and below the neutral axis is known as double cast concrete beam. The flexural response of double cast concrete beam having four point loading test arrangement was determined in the current study. The volume fraction of steel fiber was 0%, 1%, 1.5%, 2% below the neutral axis with constant aspect ratio of 80 and 15% of the concentration of fly ash was used in whole beam structure (below and above the neutral axis). M25 design mix was used for all beams. The results revealed that load carrying capacity of 1.5% volume fraction of steel fiber improved by 42.36% as compared to control beam.
