滨海环境玄武岩纤维混凝土性能研究

Study on the performance of basalt fiber concrete in coastal environment

在滨海环境下,桥梁结构易受到海水的侵蚀,容易产生各类病害,导致桥梁寿命快速缩减。对玄武岩纤维混凝土配合比进行了设计,并通过试验对玄武岩纤维混凝土的抗弯拉强度、劈裂抗拉强度、立方体抗压强度以及抗渗性能进行了研究。结果表明,玄武岩纤维混凝土具有抗裂性能好、韧性较高、抗渗性好等优点。

In coastal environments,bridge structures are susceptible to seawater erosion,can easily produce various types of diseases and lead to rapid reduction of bridge life.Basalt fiber concrete proportions were designed,and the flexural tensile strength,splitting tensile strength,cubic compressive strength and seepage resistance of basalt fiber concrete were studied through tests.At the same time,the cost and economic benefits of basalt fiber concrete were analyzed.
