Enhancing corrosion resistance in concrete structures using Euphorbia Tortilis cactus extract by non-destructive testing

This research investigates the corrosion resistance of reinforced concrete structures, a crucial aspect for ensuring their long-term performance and sustainability. Utilizing both the half-cell potential method and an accelerated corrosion test, the study introduces a novel approach by incorporating Euphorbia Tortilis Cactus (ETC) extract as an organic additive in concrete. The half-cell potential method involves measuring potential differences between steel reinforcement and an external electrode in a Cu/CuSO4 solution, revealing varied corrosion inhibition levels in different specimens. Notably, the introduction of ETC extract demonstrates unprecedented resistivity, showcasing a mere 10% probability of corrosion, even in atmospheric conditions. The accelerated corrosion test further emphasizes the novelty of the research. ETC concrete exhibits lower applied current and mass loss percentages compared to control mixes, indicating superior corrosion resistance and reduced porosity. This novel use of ETC extract in concrete enhances its durability and sustainability, providing valuable insights for developing resilient concrete structures amid increasing concerns about corrosion-induced deterioration in reinforced concrete constructions.
