摘要: 讨论了玄武岩纤维与聚丙烯纤维的“纤维混杂效应”对混凝土基体力学性能的影响。结果表明,玄武岩-聚丙烯混杂纤维混凝土(B-P HFRC)的劈裂抗拉强度和抗折强度明显高于玄武岩纤维混凝土(B FRC)和聚丙烯纤维混凝土(P FRC)。提出了“纤维混杂效应函数”的概念,利用MATLAB数据拟合的方法求得了玄武岩-聚丙烯纤维混杂效应函数,对其求极值获得了玄武岩-聚丙烯混杂纤维对混凝土力学性能改善最佳的体积掺加率。

Abstract: The influence of "hybrid effect" caused by the basalt fiber and polypropylene fiber on the mechanical properties of the concrete of matrix is discussed. The results show that the splitting tensile strength and flexural strength of basalt-polypropylene hybrid fiber reinforced concrete (B-P HFRC) is obviously higher than those of basalt fiber reinforced concrete (BFRC) and polypropylene fiber reinforced concrete (PFRC). Meanwhile, the concept of "fiber hybrid effect function" was proposed. The hybrid effect function of basalt-polypropylene hybrid fibers is obtained by the method of MATLAB data fitting. By confounding the "the hybrid effect function of basalt-polypropylene hybrid fibers" extremum the optimum basalt-polypropylene hybrid fibers volume mixing ratio, which improves the mechanical properties of concrete, was obtained.

Key words: basalt fiber, polypropylene fiber, hybrid fiber reinforced concrete, hybrid effect function
