采用线性极化电阻法研究了温度对钢筋在模拟海砂混凝土孔隙溶液中氯离子腐蚀行为的影响。结果表明，钢筋的腐蚀电位和腐蚀电流密度与温度和氯离子浓度有关。Ecorr与温度呈线性相关，icorr与CCl呈自然对数相关。结果表明，腐蚀速率与温度的关系符合Arrhenius方程，而腐蚀反应活化能随CCl含量的增加而增大。
The effects of temperature on the chloride-induced corrosion behavior of reinforcing steel in simulated sea-sand concrete pore solution are studied by means of linear polarization resistance. The results show that the Ecorr (corrosion potential) and icorr (corrosion current density) of the reinforcing steels are temperature and/or chloride concentration (CCl)-related parameters. A linear correlation between Ecorr and temperature and a natural logarithmic correlation between icorr and CCl are observed. It is proved that the relationship between the corrosion rate and temperature follows the Arrhenius equation, whereas the activation energy of corrosion reaction increases with the increase of CCl.
