腐蚀环境下玄武岩纤维混凝土性能的研究

Study on Basalt Fiber Concrete Performance in Corrosive Environment

为研究玄武岩纤维对混凝土性能的影响规律,将含有不同玄武岩纤维的混凝土试件置于单一硫酸盐环境、硫酸盐和氯盐共同环境中进行浸泡腐蚀试验,测试了不同腐蚀环境中混凝土抗压、抗折强度随浸泡时间和玄武岩纤维含量的变化规律。结果表明:单一硫酸盐腐蚀环境中混凝土抗压、抗折强度随着玄武岩纤维掺量的增加呈现降低的趋势。硫酸盐和氯盐共同腐蚀环境中玄武岩纤维混凝土抗侵蚀的能力强于单一硫酸盐腐蚀环境中玄武岩纤维混凝土的抗侵蚀能力,掺入玄武岩纤维提高了混凝土在硫酸盐和氯盐共同腐蚀环境中的抗折性能。

In order to study the influence of basalt fiber on properties of concrete,containing different basalt fiber concrete immersion corrosion test of single piece in the sulfate environment,sulfate and chloride in the common environment,tested the different corrosion environment of concrete compressive strength,flexural variation with immersion time and basalt fiber content. The results show that：Single sulfate corrosion environment of concrete compressive,flexural strengthdecrease with increase of the admixture of basalt fiber.The anti erosion ability of basalt fiber sulfate and chloride corrosion of concrete in the environment of antierosion ability in basalt fiber single sulfate corrosion environment of concrete,the incorporation of basalt fiber to improve the fracture resistance of concrete insulfate and chloride corrosion of energy in the environment.
