摘　　要：采用正交试验研究再生骨料掺量、粉煤灰掺量、减水剂掺量以及加入不同种类的纤维4个配合比参数对纤维再生混凝土抗冻性能的影响,得出满足再生混凝土(设计强度C35)良好抗冻性的最佳配合比。试验结果表明:当再生骨料掺量为50%、粉煤灰掺量为10%、减水剂掺量为0.5%,选用铣削波纹型钢纤维时,再生混凝土可满足强度及良好抗冻性能。The influences of four proportion factors, including the mix quantities of regenerated aggregate, fly ash, water reducing agent and various sorts of fiber, on the mechanical properties of fiber recycled concrete were analyzed, which was the frost resistance of recycled concrete by utilizing the orthogonal testing method.The results indicated that the strength and frost resistance of recycled concrete could satisfy performance requirements.
