This paper is aimed at investigating the shear strength and work ability characteristics of Fiber Reinforced High Strength Concrete (FRHSC) which use recycled coarse aggregates that have originated from demolished construction wastes. Different mixes were taken with 0%, 20% , 40% , 60% , 80% and 100% replacement of natural coarse aggregate with recycled coarse aggregate.To improve the ductility and performance, 1% steel fiber is also added to the concrete. The shear strength of FRHSCmixes was obtained by casting and testing double –L (push-off) specimens after curing for 28 days. The effect of replacement of natural granite aggregate with recycled coarse aggregate on shear strength and workability of FRHSC has been evaluated at length in this paper
