Behavior and Performance of Reinforced Concrete Columns Subjected to Accelerated Corrosion

Steel reinforcement corrosion in concrete structures such as bridges, industrial plants, marine structures, and coastal buildings is a growing concern due to its impact on cost, safety, serviceability. Corrosion leads spalling, cracking, reduced diameter, which can compromise structural integrity. This study examines the behavior of columns with corroded two phases. In first phase, 72 150 × mm cross-sectional dimensions 300 length were cast subjected an accelerated technique. The examined variables cover, strength, exposure. second phase involved studying axial concerning effect column length. Column specimens lengths 500 mm, 700 900 cast, corroded, tested under compressive load. revealed that 30 cover offers 10% more protection against than 20 cover. Continuous exposure corrosive environment reduces load-carrying capacity by 50%, while 28 MPa strength carry 4% Longer are susceptible corrosion, leading significant reduction damage. Therefore, maintaining adequate regular inspections essential address steel preserve
