Developing population and increasing housing need cause the proliferation of reinforced concrete structures. On the one hand, while trying to build durable structures, on the other hand, environmental solutions are sought. When the literature studies are examined, it is stated that corrosion is primarily an environmental pollutant. In general, corrosion inhibitors are used because they are more economical and application methods are easier. It is stated that corrosion inhibitors may show toxic effects during production, use or disposal. The aim of this article is to investigate the effects of eco-friendly green corrosion inhibitors, apart from the common methods used against corrosion, which adversely affects the durability of reinforced concrete structures. When the literature studies are examined, it is seen that eco-friendly green corrosion inhibitors are obtained from various plant extracts, oils, biopolymers and nature.

In this study, the effects of green corrosion inhibitors on reinforcement corrosion as well as the effects on cement mortars are examined. Electrochemical corrosion measurement methods on the reinforcement are examined, as well as weight losses are determined. In cementitious mortars, on the other hand, mechanical properties, durability losses in aggressive medium conditions and microstructure studies are investigated. Thus, it is aimed to examine the eco-friendly green corrosion inhibitors in concrete and steel reinforcement in reinforced concrete structures. When the results are examined, the methods of obtaining the environmentally friendly green corrosion inhibitors and their optimum dosages are determined.
