【摘要】 我国沿海地区因河砂缺乏,时常出现海砂未经妥善处理即拌入混凝土的情况,从而对当地钢筋混凝土结构的耐久性造成严重威胁对于已经掺入过量氯离子的既有钢筋混凝土结构,如何早发现、早处理是人们普遍关心的问题为此,系统地总结了当前国内外既有建筑混凝土中氯离子含量检测的主要方法和应用现状,并针对我国既有建筑混凝土氯离子检测的特点,对未来相关技术的发展进行了展望更多还原

【Abstract】 Because shortage of river sand at coastal area, it often occurred that sea sand without completely desalinated were added into concrete. This problem seriously threatened durability of local exiting RC structures. The best measure to solve the problem is early detection and early treatment. This paper systematically summarized current main methods and application status of chloride content test at home and abroad. Finally, for chloride test in our exiting concrete structures, some prospects of developing trend are proposed.更多还原
