沿海及盐湖地区存在的高浓度氯离子是导致混凝土中钢筋锈蚀的最主要原因,这也是导致结构混凝土破坏的根本原因之一。本文从钢筋的锈蚀机理、影响因素、发展过程以及钢筋锈蚀对粘结性的影响做全方位的阐述。 The high concentrations of chloride ions present in coastal areas and salt lakes are the major causes of steel corrosion in concrete, which is also one of the fundamental causes of structural concrete failure. In this paper, from the corrosion mechanism of reinforcing bars, the influencing factors, the development process and the influence of corrosion of reinforcing bars on the cohesion, this paper makes an all-round explanation.
