摘 要:通过四点弯曲试验,研究了冻融循环0次、50次、100次、150次、200次后聚乙烯纤维超高韧性水泥基复合材料(PE-ECC)梁的受弯性能。结果表明:PE-ECC梁的质量损失、极限荷载、跨中最大挠度均随着冻融循环次数的增加而降低,但降低程度不显著,说明冻融循环后PE-ECC梁的受弯性能退化不明显。
Abstract: Four point bending tests were carried out to study the flexural behavior of polyethylene fiber ultra-high toughness cement-based composite(PE-ECC) beams after freeze-thaw cycles of 0, 50, 100, 150 and 200. The results show that the mass loss, ultimate load and maximum deflection of PE-ECC beams decrease with the increase of freeze-thaw cycles, but the reduction degree is not significant, which indicates that the flexural performance degradation of PE-ECC beams is not obvious after freeze-thaw cycles.
