This paper describes the influence of recycled materials on the flowability of steel fiber-reinforced cement composites. For the FRCC, fly-ash and recycled sand were used as recycled materials. The recycled materials were mixed with replacement ratios of 25% and 50%. As reinforcing fiber for the FRCC, micro steel fibers were used. Based on the test results, flowability of FRCC was improved when fly-ash was replaced. Increase of recycled sand had FRCCs exhibited lower flowability.
