【摘要】 混凝土导电性能高低不仅影响钢筋混凝土的耐久性,而且也可利用其作为混凝土其他性能的测量手段,因此混凝土导电性的研究与应用得到越来越多的关注。分析总结了混凝土导电机理及其影响因素,介绍了混凝土导电性能在混凝土氯离子渗透、耐久性以及凝结时间测试方面的应用,同时分析了混凝土导电性应用中可能存在的问题。认为导电性测试有望成为混凝土耐久性在役监测的简便有效手段。更多还原

【Abstract】 The capacity of electrical conductivity not only affects the durability of reinforced concrete but also can be used as an indirect testing parameter on evaluating some properties of concrete easily. Therefore, much attention has been paid to the electrical conductivity of concrete. The mechanism and influencing factors of the electrical conduction in concrete are reviewed, and some prospective applications of concrete electrical conductivity are introduced in brief. Some potential problems and future directions related to concrete electrical conductivity are suggested. It is concluded that the electrical conduntivity measurement will become an effective method to monitor the durability of concrete under use.更多还原
