摘要：研究了玄武岩纤维（BF）掺量对掺沙漠砂混凝土抗压强度、单轴受压应力-应变曲线、劈裂抗拉强度和弹性模量的影响。结果表明：BF对掺沙漠砂混凝土的抗压强度和弹性模量影响较小；掺沙漠砂混凝土的劈裂抗拉强度随着BF掺量的增加呈先增大后减小的趋势，BF最佳掺量为0.4%；BF掺沙漠砂混凝土的应力-应变曲线发展规律与普通混凝土类似；采用普通混凝土的弹性模量计算公式能较准确地计算出BF掺沙漠砂混凝土的弹性模量。 Abstract: The effects of basalt fiber(BF) content on compressive strength, uniaxial compression stress-strain curve, splitting tensile strength and elastic modulus of concrete mixed with desert sand were studied. The results show that BF has a little effect on the compressive strength and elastic modulus of concrete mixed with desert sand. The splitting tensile strength of concrete with desert sand increases first and then decreases with the increase of BF content, and the optimum BF content is 0.4%. The stress-strain curve of BF concrete mixed with desert sand is similar to that of ordinary concrete. The elastic modulus of BF concrete mixed with desert sand can be calculated accurately by using the elastic modulus formula of ordinary concrete.
