In this paper, the flexural behavior of hybrid fibre reinforced concrete beams was investigated. Two types of hybrid fibres were used. used in this study, one is having high young’s modulus steel fibre (Hooked end) and another one is having low young’s modulus Polypropylene fibre with different proportions. Nine types of reinforced concrete beams were made by using M50 grade high strength concrete mix a volume factors of hybrid fibres as 1.5%. this beams includes conventional concrete, LC3 concrete and he beam with the following combinations of hybrid fibres such as OPC 100%, LC3 100%, SF100%, SF25% -PF75%, SF40%-PF60%, SF50%-PF50%, SF60%-PF40%, SF75%-PF25 %, PF100%, the working results shows that percentage proportion of combined SF-PF at 75%-25% had the best implementation on its flexural strength. Experimental results also shows that beam with SF75%-PF25% had their structural stiffness, ductility index and energy absorption capacity have been improved the most as compared with the conventional concrete and other fibre combinations of beams.
