为了研究不同类型混凝土的硫化腐蚀性能,笔者以不同水灰比、粉煤灰掺量及不同粗集料的混凝土为研究对象,分别对二氧化硫腐蚀环境下各类型混凝土的质量损失、抗压强度和硫化深度展开详细研究,获得了混凝土的硫化腐蚀规律。结果表明:在普通混凝土中,水灰比越大抗硫化腐蚀能力越优;适量掺入粉煤灰,能有效提升混凝土的抗硫化腐蚀性能;轻集料混凝土在质量损失和抗压强度两方面低于普通混凝土。
In order to study the sulfidation corrosion performance of different types of concrete, the author takes concrete with different water-cement ratio, fly ash content and different coarse aggregate as the research object, and separately analyzes the quality loss, compressive strength and compressive strength of various types of concrete under the environment of SO2 corrosion Vulcanization depth of a detailed study, access to the vulcanization of concrete corrosion law. The results show that: in ordinary concrete, the greater the ratio of water to cement is, the better the capability of anti-sulfidation corrosion is; the proper amount of fly ash can effectively improve the anti-sulfur corrosion resistance of concrete; the light aggregate concrete has a great effect on both quality loss and compressive strength Lower than normal concrete.
