To investigate the possibility of replacing natural fine aggregate (NFA) with fine recycled aggregate (FRA), cement concrete with different FRA contents (0%, 25%, 50%, 75%, 100%) at 1% steel fiber admixture was configured and the compressive strength, tensile properties, stress-strain properties and durability performance of the formed specimens were determined. The results show that: replacing NFA with FRA leads to a decrease in the mechanical strength of fine recycled aggregate cement concrete; the addition of 1% steel fiber significantly enhances the splitting tensile strength and flexural strength of fine recycled aggregate cement concrete, increases the peak stress by about 15%, increases the peak strain by 50%, and increases the toughness and ductility by about 5 times; the optimum content for replacing NFA with FRA can be maintained at approximately 50%.
