摘要 研究了混凝土电阻率的测试方法及主要影响因素,对混凝土电阻率在钢筋混凝土耐久性评价中的应用进行了评述,认为混凝土电阻率不仅能较好反映与渗透性密切相关的混凝土密实度和孔结构,而且能反映混凝土腐蚀损伤程度和钢筋锈蚀速度,提出以混凝土电阻率为损伤变量对遭受腐蚀的混凝土结构进行耐久性的量化评估和寿命预测。 Research on caculating and testing methods of elecUical resistivity of concrete are carried out. Effects of concrete materials, water to cement ratio and environmental factors on electrical resistivity are summarized according tO research achievements and experimental resuits. Application of resistivity parameter in durability estimation of reinforced concrete are reviewed. Analysis and suggestions of electrical resistivity of concrete as a damage variable for service life prediction and durability appreciation of marine concrete are provided.
