Shear resistance of high volume fly ash reinforced concrete beams without web reinforcement

Abstract

The shear strength of reinforced concrete beams without shear reinforcement made with high volume fly ash used as cement replacing material. The mix proportions of 1:1.433:2.094 with 0.32 water/binder ratio was adopted in this study. The shear span to depth (a/d) 2.50 was kept constant throughout the experiments. The longitudinal tensile steel reinforcement 0.58%, 1.0%, 2.0% and 2.95% was used in the RC beam specimens. The mechanical properties such as compressive strength, split tensile strength were also studied along with beam specimens. The experimental shear stress values were compared with control concrete, codes of practices and other empirical formulae.
