摘要
设计了不同钢筋腐蚀率的混凝土试件,试验研究环境温度和湿度对钢筋腐蚀电位的影响。结果表明,钢筋腐蚀电位随环境温度和湿度的增大而减小。根据试验结果拟合分别建立了环境温度和湿度与钢筋腐蚀电位的定量关系,可为现场混凝土中钢筋腐蚀电位检测结果的修正提供依据。
Concrete specimens with different corrosion levels of reinforcing bars were tested,and effect of temperature and humidity on half-cell potential of reinforcing bars in concrete was investigated.Experimental results show that half-cell potential decreases with increasing of environmental temperature and humidity.Then the linear relationships between half-cell potential of reinforcing bars in concrete and temperature and humidity were established,respectively.And the relationships can be used to modify the half-cell potentials measured in situ.
