| 摘 要： | 试验研究了单掺不同掺量钢纤维和聚丙烯纤维对水工混凝土抗冻融性能的影响.试验结果表明:一定掺量下,2种纤维混凝土的抗冻性能均优于基准混凝土;聚丙烯纤维对水工混凝土抗冻性能的提高较为显著;单掺1kg/m3聚丙烯纤维对水工混凝土抗冻性能改善效果最好,经过300次冻融循环后相对动弹性模量达到85.5％,质量损失率仅为1％.

| Abstract: | The research is carried on aiming at freezing-thawing resistance of different contents of steel fibers and polypropylene fibers to hydraulic concrete.The results show that the freezing-thawing resistance of two types fibers concrete was better than ordinary concrete.The improvement of freezing-thawing resistance of polypropylene fibers is more notable than hydraulic concrete.Adding 1 kg/m3 polypropylene fibers could achieve the best improving effect of frost resistance of hydraulic concrete,the relative dyn... |
