摘 ? 要：通過三分點加載試驗，研究了玄武巖纖維體積摻量（0、0.25%、0.50%、0.75%、1.00%、1.25%）和長度（6 mm、12 mm）對混凝土彎曲性能的影響。結果表明：長度為12 mm的玄武巖纖維對混凝土抗彎強度的改善效果較好；隨著玄武巖纖維摻量的增加，試件的抗彎強度先增后減，且玄武巖纖維的最優摻量為1.00%；玄武巖纖維雖可改善混凝土的等效初始彎曲強度，但對初始彎曲韌度比影響較小，即對峰值荷載前的彎曲韌性改善效果較小。
Abstract: Through three-point loading test, the effect of basalt fiber volume content（0、0.25%、0.50%、0.75%、1.00%、1.25%） and basalt fiber length（6 mm、12 mm） on the flexural properties of concrete was studied. The results show that basalt fiber with the length of 12 mm is more beneficial to bending strength. With the increase of basalt fiber content, the bending strength of concrete first increases and then decreases, and the optimal basalt fiber content is 1.00%. Although basalt fiber can improve the equivalent initial bending strength of concrete, it has little effect on the initial bending toughness ratio, which means there is no obvious improvement of bending toughness before peak load.
