Abstract :
Civil construction projects have always met with corrosion issues affecting reinforcements, both in circumstances where the relevant standards were not observed during concrete design and preparation and in structures close to bridges, coasts, ports, quays and so on, where exposure to an aggressive environment can lead to damage such as rust spots, cracking and delamination of the concrete cover, which constitutes a hazard for the end-user. Inhibitors are frequently simple to apply and extensively utilised to reduce the corrosion rate of many steel structures in the aggressive environments without causing any significant disruption to the process. The article reviews information related to the mechanism of corrosion prevention methods to increase the service life of structures in coastal areas. This is included commercial inhibitors (inorganic and organic), sealers and barriers, eco-friendly inhibitor, and green inhibitor combined with nanoparticles. An analysis of the published literature demonstrates a general agreement that one of the most significant problems affecting reinforced concrete structures is corrosion of the steel reinforcements.
