<br/><br/> The Experimental Investigation was conducted for the monitoring of mechanical properties of the steel fiber reinforced recycled aggregate concrete beams. The study was performed through the implementation of eight concrete mix. The difference in the concrete mix was the steel fibers volume and recycled aggregate replacement ratios. The steel fibers volume fractions were varied by 0 %, 0.5%, 0.8%, 1%, which is the upper limit of the ratio according to the ASTM A Clause 820. The recycled aggregate replacement ratio was 0 %, 50%, 100 %.The effect of steel fibers, recycled aggregate, combination of steel fibers and recycled aggregate was obvious on the concrete. This effect was declared on the mechanical properties and flexural behavior of the reinforced beams.The ductility and stiffness behavior are presented along with other mechanical properties of the research concrete beams
