摘要

目前影响钢筋混凝土桥梁结构性能的主要和最昂贵的退化类型是钢筋的腐蚀。钢筋混凝土结构的腐蚀造成了巨大的经济损失。防止钢筋混凝土结构腐蚀的一种常用技术是阴极保护。由于它可以在钢筋混凝土建筑物具有高电阻的情况下提供必要的电流,因此外加阴极保护(ICCP)提供了强度和适应性。导电涂层、分立阳极系统、胶凝覆盖层中的钛基网格、碳纤维导电覆盖层和火焰喷涂锌是通常用于外加电流阴极(ICC)的阳极材料的例子。特别是氯离子,极难渗透穿过钢上的连续环氧涂层,这使得环氧涂层成为对这些有害化学物质非常有效的屏障。环氧树脂是保护金属表面免受环境和恶劣环境影响的一个很好的选择,因为它们具有出色的防腐性能,对各种表面的良好粘附性和耐化学性。本文综述了阴极保护、ICCP、各种导电涂料以及环氧涂料作为阳极材料。

Analytical Review of Conductive Coatings, Cathodic Protection, and Concrete
The principal and most expensive type of degradation that currently affects the performance of reinforced concrete bridge constructions is the corrosion of steel reinforcement. Strong financial losses result from the corrosion of reinforced concrete structures. One popular technique for preventing corrosion in reinforced concrete structures is cathodic protection. Since it can give necessary current in a situation where reinforced concrete buildings have high resistance, impressed present cathodic protection (ICCP) provides strength and adaptability. Conductive coatings, discrete anode systems, titanium-based mesh in cementitious overlay, conductive overlay with carbon fibers, and flame-sprayed zinc are examples of anode materials that are often used for impressed current cathodic (ICC). Chloride ions, in particular, are exceedingly difficult to permeate through a continuous epoxy coating on steel, making an epoxy coating a very effective barrier to these hostile chemicals. Epoxy resins are a great option for shielding metal surfaces from the environment and hostile environments because of their outstanding anti-corrosion qualities, good adherence to a variety of surfaces, and chemical resistance. In this work, the cathodic protection, ICCP, various conductive coatings, and epoxy coating as anode material are reviewed.
