A review on the application and morphology of organic corrosion inhibitors / Olivia Rayeg ...[et.al.]

Corrosion is a major challenge in construction technology and manufacturing industry. It does not only reduce the aesthetics of a building but also weakens the structure. Structural weakness caused by rust leads to the reduction in the durability of reinforced concrete. Various efforts and research ranging from prevention to maintenance process are being carried out globally to overcome this problem. Due to the increased awareness of the importance of preserving the environment for health and ecological system, studies are increasingly focused on the use of environmentally friendly corrosion inhibitor. This paper discusses several conditioning methods of using organic corrosion inhibitors in concrete reinforcement. It also takes a close look at the effect of every conditioning method towards the reinforced concrete strength and the mechanism to improve it. The migrating and admixed corrosion inhibitors (MCI) conditioning methods is considered as the best solution so far to enhance corrosion resistance performance that contributes to superior reinforced concrete mechanical strength.
