摘　　要：玄武岩纤维是一种极具应用前景的新型高性能无机纤维。概述了玄武岩纤维的物理力学性能、环境因素作用下玄武岩纤维及其复合材料的耐久性和表面修饰对纤维性能的影响。重点介绍了玄武岩纤维在水泥基材料中的应用研究进展,其中包括玄武岩纤维混凝土准静态力学性能和韧性的理论与试验研究以及玄武岩纤维布在混凝土结构加固方面的应用。并提出了当前玄武岩纤维增强水泥基材料研究中存在的问题和今后研究的方向。Basalt fiber is a new high-performance inorganic fiber, which has a broad applied prospects. Recent studies on the physical and mechanical properties of basalt fiber, durability of basalt fiber and its composite experiencing environmental effect, and influence of surface modification are summarized. The applications of basalt fiber in cement-based materials are reported emphatically. Theoretical and experimental study on the quasi-static mechanical properties and toughness of basalt fiber reinforced concrete, and reinforced concrete structure strengthened with BFRP sheet are included. The research trends of basalt fiber reinforced cement-based materials in the future are prospected.
