摘要
利用钢纤维与高强高模量聚乙烯纤维结合,研发了新型的混杂纤维增强混凝土,对其在常温、高温条件下的力学性能展开试验研究,并得到了纤维掺量对其力学性能的影响规律。结果表明,在常温下当两者掺量比为50∶1时,混凝土抗压强度达到最大值;当温度为550℃时,混杂纤维混凝土相对抗压强度达到峰值,温度高于550℃后,混杂纤维混凝土相对抗压强度明显下降。
A new type of fiber-reinforced concrete using steel fibers and UHMWPE fibers were developed. The compressive and flexural strength of the fiber-reinforced concrete were tested under room temperature and high temperatures. The results show that the compressive strength of the fiber-reinforced concrete is highest when the fiber ratio is 50∶ 1, while its compressive strength reaches peak value when the temperature set to 550 ℃.
