    Abstract

    In order to improve the mechanical properties of recycled aggregate concrete (RAC), waste polyethylene terephthalate (PET) plastic bottles were shredded into fiber strip to prepare fiber reinforced recycled aggregate concrete (FRRAC). A series tests like slump test and strength test on FRRAC, together with RAC as reference, were performed to investigate the effects of length and content of waste PET plastic fibers on FRRAC properties. Furthermore, the significance analysis of strength influencing factors and microstructure analysis of concrete were conducted. The results show that, compared with RAC, there is a reduction in the fludity of FRRAC with the increase in length and content of waste PET plastic fibers. The compressive strength overall increases, and the splitting tensile strength significantly increases with the addition of PET fibers in RAC. The content of fibers shows significant effect on compressive strength. As for splitting tensile strength, significant effects of length and content as well as their interaction are all exhibited. Although the incorporation of PET fibers into RAC leads to weak interface transition zones, the microstructure of FRRAC is denser than RAC.
