玄武岩纤维混凝土耐久性研究及机理分析

Study on the durability test and mechanism analysis of basalt fiber reinforced concrete

针对北方寒区混凝土因冻融破坏而影响混凝土耐久性的问题,通过在混凝土中掺入适量玄武岩纤维进行试验研究,从混凝土的抗渗和抗冻性能指标来研究玄武岩纤维混凝土对耐久性能的影响,并分析了其影响机理,实践证明:采用该方法提高了混凝土结构的耐久性,值得推广。

For the durability problem of concrete because of freeze-thaw damage in north cold area, the test is studied mixing certain amount of basalt fibers in concrete, researches the effect of basalt fiber on the durable performance of concrete from the impermeabihty and frost resistance and the reason why basalt fiber has effect on concrete is analyzed, practice proves that ： mixing basalt fiber reinforced method can improve the du- rability of concrete structure. Thus, it is worth promoting.
