汕头某住宅楼混凝土柱角开裂检测分析

DETECTION AND ANALYSIS OF CRACKED CONCRETE COLUMN FOR A DWELLING BUILDING IN SHANTOU

通过检测混凝土中氯离子含量、混凝土保护层厚度和钢筋锈蚀程度等方法,分析和探讨汕头某住宅楼混凝土柱角顺筋开裂的原因。结果表明,使用盐水养护造成混凝土中氯离子含量偏高是柱角开裂的主要原因。同时还探讨了混凝土柱中氯离子分布的规律。

The detection for concrete column cracking of a dwelling building by detecting chlorine ion in the concrete, concrete cover thickness and degree of steel-bar corrosion was completed. The result of detection and analysis indicated that the main reason of column cracking was that the content of chlorine ion in concrete was higher. The distributive rules of chlorine ion in concrete column were also discussed.
