| 摘 要： | 为了研究改性聚酯纤维对道面混凝土的阻裂性能,应用所建立的抗裂性试验方法,对改性聚酯纤维的规格和掺量的不同对道面混凝土的阻裂性能进行了室内试验研究.研究结果表明:随着纤维长度的增长和纤维掺量的增加,改性聚酯纤维对道面混凝土的阻裂效果也增加.当纤维的长度为19mm,掺量为1.25 kg/m3时,道面混凝土的裂缝而积为零.道面改性聚酯纤维混凝土具有良好的抗裂性. |

| Abstract: | In order to determine early anticrack of pavement modified polyester fiber reinforced concrete,the anticrack test was done when different length,content of modified polyester fiber by the early anticrack test method on pavement synthetic fiber reinforced.The results show that lengths,content of modified polyester fiber increases can make the creak area descend.When the length is 19 mm,the content is 1.25 kg/m3,no creak is on the surface.Pavement modified polyester fiber reinforced concrete has early anticra... |
