Flexural behaviour of steel fiber reinforced high strength rice husk ash cement concrete simply supported beams

The experimental programme was designed to study the flexural behaviour of simply supported beams cast with steel fiber reinforced high strength rice husk ash cement concrete. The variables in the study are Volume of steel fibers and longitudinal reinforcement. Twelve rectangular reinforced concrete beams are cast and tested under two-point loading. Moments and curvatures are calculated from the experimental data and the Moment-curvature diagrams are presented in this paper. From the experimental data, it is observed that the addition of steel fibers made the RC sections to behave in a ductile manner even if the sections are over reinforced.
