某住宅小区楼房地下室混凝土腐蚀研究

Study on Concrete Corrosion of a Certain Building Basement

对开裂的混凝土工程的周边环境进行检测分析,环境水中硫酸盐的腐蚀等级为中等腐蚀。运用扫描电子显微技术对受破坏混凝土进行微观检测,混凝土裂缝中有较多的钙矾石存在,该结构混凝土受到硫酸盐腐蚀破坏。

Through researching the environment of cracking of the concrete,it is found that the sulfate corrosion of environment water is medium,and there are more ettringites in the cracks of the concrete with scanning electron microscopy technology.The researching results show that the concrete is corroded by the sulfate.
