摘要:
研究了玻璃纤维、有机纤维及混杂纤维增强混凝土的弯曲疲劳特性。试验结果表明:耐碱玻璃纤维对疲劳性能的改善效果优于聚丙烯纤维; 当玻璃纤维掺量为2.7 kg·m-3时,玻璃纤维混凝土疲劳强度比素混凝土提高24%; 玻璃纤维与有机纤维混杂使用后,构件的弯曲疲劳性能有了较为显著的改善,玻璃纤维掺量2.7 kg·m-3与有机纤维掺量1.3 kg·m-3混掺时,混杂纤维混凝土疲劳强度比素混凝土提高35.0%,即混杂纤维能充分发挥各种纤维的优势, 对改善混凝土的疲劳性能比单掺玻璃纤维和有机纤维的作用都显著。
Abstract:
The flexural fatigue properties of glass fiber, organic fiber, and hybrid fibers reinforced concrete were studied. The test results show that alkali-resistant glass fiber can improve fatigue behavior of concrete; glass fiber has better effect on improving the fatigue behavior than polypropylene fiber. When the glass fiber concentrations are 2.7 kg·m-3, the flexural fatigue strength of concrete with glass fiber is 24% larger than that of plain concrete; when glass fiber and organic fiber concentrations are respectively 2.7 kg·m-3 and 1.3 kg·m-3, the flexural fatigue strength of hybrid fiber reinforced concrete is 35.0% larger than that of plain concrete; ie, hybrid fiber will have advantages of all kinds of fibers, which has more effect to improve the fatigue behavior of concrete than alone used glass fiber or organic fiber to concrete.
