加强腐蚀是损坏和与为维护,恢复和代替的随后的庞大的费用世界范围的增强的具体结构的早失败的主要原因。今天为对加强腐蚀的评价使用的许多方法基于决定免费腐蚀潜力或极化抵抗的电气化学的技术。大多数这些方法总是在 Stern-Geary 方程把 B 价值看作经常。然而, B 随着不同状况变化。在这份报纸, potentialdynamic 方法被用来描绘增强钢的腐蚀。Q235 碳钢的腐蚀率与具体环境被测量。B 被计算即时。由这样,加强腐蚀率的错误被最小化。
Reinforcement corrosion is the major cause of damage and early failure of reinforced concrete structures worldwide with subsequent enormous costs for maintenance, restoration and replacement. Many methods used today for assessment of reinforcement corrosion are based on electrochemical techniques that determine the free corrosion potential or polarization resistance. Most of these methods always consider the B value in Stern-Geary equation as constant. However, B changes with different condition. In this paper, potentialdynamic method is used to characterize the corrosion of reinforcing steel. The corrosion rate of Q235 carbon steel is measured with concrete environment. B is calculated real-time. By this way, the error of reinforcement corrosion rate is minimized.
