Abstract

Abstract

Based on the workability test of fiber reinforced self-compacting concrete， this paper presents theexperimental study on flexural behavior of seven sets of hybrid fiber reinforced self-compacting concrete beams withoutreinforcement and five sets of hybrid fiber reinforced self-compacting concrete beams with low reinforcement ratios.The influence of fiber aspect ratio and fiber type on crack load，yield load，ultimate load and flexural toughness are analyzed. The results indicate that the flexural toughness increases with increasing of fiber aspect ratio. The flexural toughness of hybrid fiber reinforced self-compacting concrete beams is better than that of steel fiber，which indicates positive hybrid effect. Compared to RC beam with a minimum longitudinal reinforcement，the yield load and ultimate load of fiber reinforced RC beams are greatly improved. The ultimate load of 40 + 4kg /m3 hybrid fiber reinforced RC beam with a minimum longitudinal reinforcement is similar to that of RC beam with 1.5 times of a minimum longitudinal reinforcement.
