Corrosion of mild steel in construction field poses safety, financial and environmental threat. It can be handled effectively using inhibitors. Despite having an advantage, the inorganic and synthetically produced inhibitors impart huge cost and toxicity. As a result of extensive research towards green technology quite significant numbers of green corrosion inhibitors from plants shows promising results at low cost and eco-friendly option. The constituents in plants acts in a similar way like its chemical counterpart and provide best inhibition efficiency. This paper provides an overview of types of corrosion, corrosion process, and mainly recent work done on the application of natural plant extracts as corrosion inhibitors for mild steel.
