THE RESISTIVITY OF CONCRETE CONTAMINATED BY CHLORIDE
-
摘要: 混凝土电阻率是影响混凝土中钢筋腐蚀速度的重要因素。针对受氯离子污染环境下的混凝土,通过试验测定在不同水灰比、相对湿度、氯离子含量下混凝土试块的电阻,换算出混凝土电阻率,并提出了受氯离子污染环境下混凝土电阻率的模型公式。Abstract: Concrete resistivity is an importmant factor affecting corrosion rate of steel in concrete.The resistance of concrete with different W/C, relative humidity and chloride ion content was tested, from which the resistivity of concrete was calculated.Finally a practical model was presented for estimating the resistivity of the concrete under chloride environment.
