| Abstract: | Aiming to improve the properties of recycled aggregate concrete(RAC), waste soft drink cans were processed as macro-fibers to produce fiber reinforced recycled aggregate concrete (FRRAC). Slump, compressive and splitting tensile tests on FRRAC, together with RAC and nature aggregate concrete(NAC) as reference, were performed to investigate the effect of length and dosage of the waste can fibers on RAC properties. The results show that the workability of FRRAC decreases with the length and dosage of the waste can macro-fibers, but little influence is observed with small dosage fibers(0.5%); the compressive strength slightly fluctuates, while the split tensile strength significantly increases with the addition of waste can macro-fibers in RAC. It is concluded that waste can macro-fibers can be used as reinforcement in RAC, which achieves environmental protection and resource utilization of solid waste. |
