中文摘要：

基于再生混凝土与纤维混凝土的研究成果，提出了废弃纤维作为再生混凝土的增强纤维，形成了废弃纤维再生混凝土。试验针对不同纤维长度、不同纤维掺量以及不同再生骨料取代率对废弃纤维混凝土的力学性能进行了测试。通过试验研究表明在再生混凝土中掺人废弃纤维可以有效改善其力学性能，提高其强度，对于提高废弃纺织纤维的利用率、建筑垃圾的再生利用具有重要的意义，达到“以废治废”的目的。

英文摘要：

Based on the research of the recycled concrete and the fiber concrete,put forward a concept that using the waste fiber as the reinforcing fiber in recycled concrete could form the waste fiber recycled concrete.It tested mechanical properties of the waste fiber recyceled concrete with different fiber length, different fiber replaced rate and different recycled aggregate replaced rate.The experimental research showed that the recycled concrete with waste fiber could effectively improve its mechanical properties and improve its strength.At the same time, it could also improve the utilization rate of waste textile fiber.It is more meaningful for the recycling of the construction waste.It is a best way to treat waste.
