The Corrosion of steel reinforcement in concrete
structures is a pervasive and formidable
challenge, leading to significant structural
deterioration and economic repercussions.
Traditional corrosion inhibitors often involve
chemicals that pose environmental concerns,
prompting a shift toward sustainable and eco-
friendly alternatives. In this context, the
exploration of plant extracts as green corrosion
inhibitors emerges as a promising avenue. The
inherent bioactive compounds present in plant
extracts offer a unique potential to combat
corrosion in a manner that is both effective and
environmentally benign. This comprehensive
review delves into the evolving landscape of
corrosion inhibition, specifically focusing on the
application of plant extracts as botanical
defenders for steel reinforcement in concrete. By
examining recent research, methodologies, and
outcomes, this review aims to provide a nuanced
understanding of the mechanisms involved in
corrosion
inhibition
by
plant
extracts.
Furthermore, the discussion encompasses the
ecological and economic advantages of adopting
plant extracts as corrosion inhibitors, thereby
highlighting the potential of integrating
sustainable practices into concrete protection
strategies. As we embark on this exploration of
botanical defenders, the aim is to elucidate the
promising developments in green corrosion
