南疆的盐渍土对混凝土的耐久性具有较为严重的影响,这给一路一带开发中的基础工程建设带来巨大危害。由于成因影响因素较多,该地区地下水的盐类分布情况较为复杂。主要归纳了硫酸盐离子对混凝土侵蚀的类型,针对基于硫酸盐作用下混凝土侵蚀的原理和检测方法进行论述,提出硫酸根离子在试件中的分布规律,为高性能混凝土抵抗盐类腐蚀提供依据。
Salty soil in southern Xinjiang has a more serious impact on the durability of concrete, which has brought tremendous damage to the basic engineering construction in the development along the way. Due to the causes of formation of many factors, the distribution of salt in the groundwater is more complicated. The types of sulfate attack on concrete are summarized. According to the principle and detection method of concrete erosion based on sulfate, the distribution rules of sulfate ion in the test specimen are proposed, which provide the basis for high performance concrete to resist salt corrosion .
