| 摘 要： | 对掺聚丙烯纤维的高强混凝土立方体试块进行了高温后残余抗压强度试验研究,分析了高温对高强混凝土残余抗压强度的影响,以及不同掺量和长度的聚丙烯纤维对高温后聚丙烯纤维高强混凝土残余抗压强度的影响。结果表明,适宜掺量和长度下,聚丙烯纤维既可抑制高强混凝土高温爆裂,又可明显提高高强混凝土的残余抗压强度,有利于改善高强混凝土的高温韧性。

| Abstract: | Residual compressive strength of high strength concrete(HSC) cube specimens mixed with polypropylene fiber after exposure to high temperature was investigated.After the specimens were heated in an electric stove,the effects of exposure temperature and dosage and length of fiber on residual compressive strength of HSC were discussed.The results show that the residual compressive behaviour of HSC incorporated with appropriate polypropylene fibers was pronouncedly enhanced. |

| Keywords: | polypropylene fiber high strength concrete elevated temperature residual compressive strength |
