混凝土结构耐久性检测技术

The test technology on durability of concrete structure

本文介绍了混凝土结构耐久性的现状,系统地介绍了混凝土结构耐久性的检测技术,主要包括:混凝土构件外观质量、内部缺陷与尺寸变形检测,混凝土强度、表层混凝土渗透性及钢筋材料性能检测,混凝土中钢筋位置、保护层厚度、钢筋锈蚀程度检测,混凝土碳化深度、氯离子侵入混凝土深度检测,特殊情况如碱一集料反应检测、杂散电流腐蚀性检测等。

The paper introduced the status on durability of concrete structure,and narrated systematically the test technologies on durability of concrete structure.It mainly included that the external appearance quality,internal defects and size deformation of concrete member,the concrete strength,permeability of surface layer concrete and material performance of reinforcing bar,the position and the depth of coverage and corrosion of reinforcing bars in concrete,the carbonization depth of concrete,incursion depth of chloridion,and the special condition such as alkali-aggregate reaction,corrosion of miscellaneous electric current.
