|Abstract: ||Self – compacting concrete (SCC) is concrete that achieves compaction under its own weight without vibrators. The investigation into the various properties of SCC has been undertaken by many researchers. The investigation into the structural performance of SCC considers the shear behavior of SCC due to the brittle nature of shear failure in SCC reinforced beams which occurs suddenly with no warning. The shear behavior of SCC beams with and without shear reinforcement has been under investigation and this paper reviews the findings from these investigations. It was found that the shear behavior of SCC cast as beams were influenced by the compressive strength, shear span- to – depth ratio, percentage of longitudinal reinforcement and percentage of shear reinforcement. The aggregate interlock which forms the major contribution to shear strength of beams without stirrups in SCC is found to be reduced as coarse aggregate content in SCC compared NC is also reduced. Also the cracking behavior which affects the structural performance of SCC is found to be improved by the addition of fiber. In view of that, palm kernel fiber which occurs in abundance as by product from oil produced from palm kernel would be used as fiber reinforcement to improve the cracking behavior and hence structural performance of SCC as in the benefit of the use steel and glass fiber.|
