摘要

摘要: 钢筋锈蚀速率是评估钢筋混凝土耐久性的重要参数,采用线性极化检测仪GECOR 6对实验室制作的钢筋锈蚀试件进行检测,得到了钢筋锈蚀电流密度、电位(相对于饱和硫酸硐电极)与电阻的数据。发现在一般大气环境下电氯离子侵蚀引起的钢筋锈蚀,其锈蚀电流密度与锈蚀电位、电阻等存在一定关系。特别是利用失重法对线性极化检测的结果进行了校核,发现检测结果与校核值之间存在着一定的误差。提出的修正公式,用锈蚀电位修正锈蚀电流密度,可得到较为满意的结果。

Abstract: Corrosion rate is an improtant parameter for durability of the reinforcement.Linear polarization device GECOR 6 is used to detect concrete specimens with corroded rebars made in the lab.Corrosion rate, corrosion potential and the electronic circuit resistance are gotten.The regression model is developed according to the data of the test in chloride- induced corrosion of the reinforcement in normal atmosphere.Specially losing weight method is used to calibrate the results linear of polarization and find the error between the calibrated value and the inspected corrosion rate.An empirical formula is given to modify the corrosion rate and get a satisfactory result.
