Performance Evaluation Of Reinforced Concrete Under Accelerated Acidic And Saline Corrosion Conditions

Corrosion of steel reinforcement is one of the most severe durability issues in concrete structures exposed to aggressive environments. This study investigates the performance degradation of reinforced concrete when subjected to accelerated acidic and saline corrosion environments. An experimental program was conducted using reinforced concrete specimens immersed in sulfuric acid and sodium chloride solutions under controlled conditions. Electrochemical techniques, mass loss analysis, and compressive strength tests were employed to evaluate corrosion intensity and structural degradation. The
results demonstrated that acidic environments led to rapid surface deterioration, while chloride-induced corrosion
accelerated internal steel degradation. The study highlights the comparative impacts of acidic and saline attacks and
proposes potential mitigation strategies for enhanced durability. Keywords: Reinforced concrete, corrosion, acidic environment, saline environment, accelerated testing, durability, electrochemical testing
