Experimental Study of Corrosion Behavior of Steel Reinforcement in Concrete

Corrosion of steel reinforcement in concrete structures is one of the most common causes of degradation, leading to reduced service life, structural damage, and increased maintenance costs. This experimental study investigates the corrosion behavior of steel reinforcement in concrete, under various exposure conditions such as chloride-induced corrosion, carbonation, and sulfate attack. The study aims to provide insights into the factors influencing corrosion rates, such as the concrete mix design, curing conditions, and environmental factors. Through accelerated corrosion tests and electrochemical techniques like Linear Polarization Resistance (LPR) and Electrochemical Impedance Spectroscopy (EIS), the corrosion resistance of steel rebars in concrete is analyzed. The results of the study help in understanding the mechanisms of corrosion and offer recommendations for mitigating its effects, improving the durability and longevity of reinforced concrete structures.
