Summary:

Corrosion of reinforcements often limits the durability of reinforced concrete structures, because of chloride ions or as a result of carbonation. Corrosion of reinforcement has huge economic implications as well as social issues including endangering the safety of people who are working in industries. Corrosion inhibitors control the corrosion of steel reinforcements without significantly changing the concrete properties. The environmental toxicity of the synthesized corrosion inhibitors has resulted in the search for finding green corrosion inhibitors with lower amount of toxic compounds. The corrosion inhibitors extracted from the plant products are inexpensive, readily available and renewable. Most parts of plants such as leaf, fruits peel, etc., are rich of the compounds that give them the capability to be used as corrosion inhibitor for various substrates in different electrolytes. NATCON project aims to examine the synergistic effect of some plant extracts and common inorganic inhibitors to enhance the corrosion control of the embedding steel bars in concrete.
