建设用砂氯离子检测研究

Study on Detection of Chloride Ion in Construction Sand

在建筑工程的施工过程中,如果发生了钢筋腐蚀现象,很有可能导致混凝土的结构被破坏,从而使其结构功能受到损害,就不能发挥出其应有的效果。而这种现象出现的主要原因就是因为建筑原材料中的氯离子含量过高。氯离子含量过高会使得钢筋表面的膜层受到破坏,混凝土的保护层也会出现裂缝,就无法发挥防止腐蚀的功能,从而进一步加快了钢筋腐蚀的速度,使得整个建筑工程的安全质量受到冲击。基于此,必须重视对建筑用砂氯离子含量的检测工作。

In the construction process of construction projects, if the corrosion of steel bars occurs, it is very likely that the structure of concrete will be damaged, so that its structural function will be damaged, and it will not be able to play its due effect. The main reason for this phenomenon is that the chloride ion content in the construction raw materials is too heavy. If the chloride ion content is too high, the film layer on the surface of the steel bar will be damaged, and the protective layer of the concrete will be cracked, which will not be able to play the function of preventing corrosion, thus further accelerating the corrosion rate of the steel bar, and making the entire construction project safe and quality. be impacted. Based on this, the detection of chloride ion content in construction sand must be taken seriously.
