Analysis on behavior of RCC structure under corrosion with respect to crack Available to Purchase

Reinforced concrete remains a widely adopted construction material, owing to its accessibility and adaptability in key structural elements such as beams, columns, slabs, and foundations. However, the corrosion of steel reinforcement within concrete poses a significant risk by weakening the bond strength between the steel and concrete, ultimately compromising the overall strength and durability. This research investigates the impact of chloride-induced corrosion through the use of Half-cell potential, Salt spray, and Weathering techniques on reinforced concrete specimens, which were cast with M20 grade ordinary Portland cement. Additionally, the mechanical properties of the concrete and steel are analyzed through Universal Testing Machine (UTM) assessments of the load and deflection behavior of beam specimens. The experimental results demonstrate a considerable reduction in yield point and flexural strength, ranging from 10% to 30%, for the corroded bars depending on their diameter. The findings contribute vital insights into the detrimental effects of corrosion on the shear and flexural strengths of reinforced concrete beams, thereby facilitating a comprehensive understanding of the corrosion-induced damage within concrete structures. Furthermore, this research offers guidance for the construction industry to develop effective strategies for corrosion prevention and mitigation, and encourages the exploration of more durable and corrosion-resistant materials and technologies in construction applications.
