【摘要】 通过聚丙烯纤维高强混凝土的力学性能试验,研究了聚丙烯纤维掺量对高强混凝土抗压强度、劈拉强度、弹性模量以及尺寸效应等的影响。结果表明,聚丙烯纤维对高强混凝土的抗压强度和弹性模量影响较小,但可提高高强混凝土的劈拉强度;聚丙烯纤维高强混凝土的抗压和劈拉强度都具有明显的尺寸效应。更多还原

【Abstract】 Based on the test of polypropylene fiber reinforced high strength concrete, the effect of polypropylene fiber quantity on compressive strength, splitting tensile strength, elastic modulus and dimensional effect were researched. The results indicated that the effect of polypropylene fiber on compressive strength and elastic modulus can be neglected, but the fiber can increase the splitting tensile strength of high strength concrete. The dimensional effect of compressive and splitting tensile strength of polypropylene fiber reinforced high strength concrete is obvious.更多还原
