玄武岩纤维混凝土材料性能研究进展

Research progress of the material properties on basalt fiber reinforced concrete

论述了玄武岩纤维的特点与优势,总结了玄武岩纤维混凝土的几种基本性能,分别从力学性能、耐久性、耐高温性能、动态冲击等方面阐述了国内外发展现状,提出了玄武岩纤维混凝土存在的主要问题,并对玄武岩纤维混凝土的发展前景进行了展望。归纳已有的研究结果,初步得到以下结论:在混凝土中合理的掺入玄武岩纤维,可在保留混凝土抗压强度高等优点的同时,明显的增加了其抗拉、耐久、耐高温和抗冲击等性能,可在混凝土工程应用中起到增强增韧、延长使用寿命等作用。

Discussed the characteristics and advantages of basalt fiber and summarized several basic properties of basalt fiber reinforced concrete.And the development status of basalt fiber at home and abroad was elaborated about the mechanical properties, durability, high temperature resistant performance, dynamic impact etc.The main problems of basalt fiber reinforced concrete were put forward and the prospects of basalt fiber were discussed.There are preliminary conclusion on the basis of the existing research results that when basalt fiber is incorporated reasonably into the concrete, the advantages of high compressive strength of concrete can be re- tained, and the tensile strength, durability ,high temperature resistant and impact resistance and other properties are also greatly increased simultaneously.When basalt fiber is used reasonably, the concrete can be strengthened and toughened, and the service life can be extend- ed in the engineering application.
