越来越多的混凝土结构正在受到监测，以提高其耐久性。然而，文献只对监测结果的解释提供了一些指导[Broomfield JP]。钢筋在混凝土中的腐蚀，了解调查和修复。第2版。英国：Taylor & Francis；2006年;安德拉德C，阿隆索C.钢筋腐蚀速率的现场测量。建筑材料；2001;15(2-3):141-45；En 206 2000。混凝土。第1部分：规格、性能、生产和合格性[m]。过去的经验表明，由于温度和湿度的影响，很难解释收集到的数据，也很难利用这些数据预测任何变质过程的未来演变。本文介绍了几个关于腐蚀电位、电阻和腐蚀速率的记录数据的例子，以及一种获得具有代表性的腐蚀速率的方法，平均每年。代表性值可用于腐蚀预测模型中，计算剩余使用寿命。2009爱思唯尔有限公司版权所有。
An increasing number of concrete structures are being monitored to enhance their durability. However, the literature provides only some guidance for the interpretation of the monitoring results [Broomfield JP. Corrosion of steel in concrete, understanding investigation and repair. 2nd ed. UK: Taylor & Francis; 2006; Andrade C, Alonso C. On-site measurements of corrosion rate of reinforcements. Constr Build Mater 2001;15(2-3):141-45; EN 206 2000. Concrete-Part 1: specification, performance, production and conformity]. Past experience shows the difficulty of interpreting the data collected due to the influence of temperature and moisture, and of using these data to predict future evolution of any deterioration processes.This paper presents several examples of recorded data for corrosion potential, electrical resistance and corrosion rates, along with a methodology to obtain a representative corrosion rate, averaged per year. The representative value can be used in corrosion predictive models to calculate the remaining service life. (C) 2009 Elsevier Ltd. All rights reserved.
