摘　　要：钢筋混凝土腐蚀已成为全世界土木工程界所关注的重大技术问题,在当今被确认是影响混凝土结构耐久性的首要原因,氯离子渗透腐蚀是引起钢筋混凝土腐蚀的首要原因,针对既有混凝土结构修补体系涉及的耐久性问题,通过试验研究了水灰比、掺合料以及界面处理方式对新老混凝土中氯离子渗透机能的影响,为混凝土耐久性研究提供了重要依据。Reinforced concrete corrosion has become a worldwide concern of civil engineering the major technical issues.It is identified today the primary reasons for the durability of concrete structures,then the reinforced concrete corrosion is mainly caused by chloride ion penetration.For existed concrete structural durability of repair system involved,we have studied the water-cement ratio,admixture and interface treatments impact to the function of chloride ion penetration in new and old concrete.and provided an important basis for concrete durability research.

关 键 词：新老混凝土 氯离子 渗透机能 耐久性
