摘 要:研究了不同掺量(0、0.3%、0.5%、0.7%、0.9%和1.1%)的竹叶纤维对混凝土工作性和力学性能的影响。结果表明:随着竹叶纤维掺量的增加,混凝土的坍落度逐渐降低;混凝土吸水率随着竹叶纤维掺量增加而增加;竹叶纤维的掺入对混凝土抗压强度不利,但有利于提高混凝土的劈裂抗拉强度和抗折强度;综合考虑各种因素,建议竹叶纤维的最佳掺量取0.7%。
Abstract: The effects of bamboo leaf fiber with different content(0, 0.3%, 0.5%, 0.7%, 0.9% and 1.1%) on the workability and mechanical properties of concrete were studied. The results show that with the increase of bamboo leaf fiber content, the slump of concrete gradually decreases. The water absorption rate of concrete increases with the increase of bamboo leaf fiber content. The incorporation of bamboo leaf fiber is unfavorable to the compressive strength of concrete, but it can improve the splitting tensile strength and flexural strength of concrete. Considering various factors, it is recommended that the optimal content of bamboo leaf fiber is 0.7%.
