高强玄武岩纤维混凝土的力学性能研究

Study on the mechanical properties of high-strength basalt fiber concrete

为了改善高强混凝土的力学性能,在C60混凝土中掺入一定量的玄武岩纤维,研究了纤维掺量的改变对高强混凝土力学性能的影响。通过抗压强度、抗折强度、劈裂抗拉强度和轴心抗压强度试验结果可以看出:玄武岩纤维对抗压强度提高有限,对抗折强度、劈裂抗拉强度和轴心抗压强度提高幅度较明显。

In order to improve the mechanical properties of high-strength concrete, it mixes certain amount of basalt fiber into C60 concrete, and studies the impacts of fiber mixing amount change on the mechanical properties of high-strength concrete. Through the experimental results of compressive strength, bending strength, rupture strength, and axial compressive strength, we know that： the improvement of compressive strength is limited for basalt fiber, but it has obvious improving effect for bending strength, rupture strength and axial compressive strength.
