The inhibition synergism of some plant extracts and common inorganic inhibitors to enhance the corrosion control of the embedding steel bars in concrete

Project description

Natural and inorganic inhibitors for reinforced concrete

Concrete structures are usually reinforced with embedded steel ribs. However, these reinforcements are threatened by corrosion that reduces the durability of the entire concrete structure. Although the high alkalinity of concrete produces a protective environment for steel, aggressive attacks of chloride ions or carbonisation processes represent a risk of corrosion. Corrosion inhibitors represent a method that mitigates steel bar corrosion, but synthesised inhibitors are toxic for the environment, making research on green corrosion inhibitors instrumental. Natural inhibitors extracted from the plant products emerge as the ideal solution. The EU-funded NATCON project will study the synergistic effects between common inorganic inhibitors and some plant extracts to strengthen the corrosion monitoring of the embedded steel bars in concrete constructions.
