A review on the impact of concrete corrosion and effective mitigation strategies

Abstract

This review manuscript investigates the environmental and structural challenges associated with concrete corrosion, focusing on the diverse factors contributing to the deterioration of concrete structures. The study examines various types of corrosion, including chloride-induced corrosion, microbiologically influenced corrosion (MIC), and sulfate attacks, all of which are accelerated by environmental conditions such as moisture, temperature fluctuations, and exposure to marine environments. The environmental impacts of concrete corrosion are profound, including water and soil pollution, increased waste generation, and depletion of natural resources. Case studies from different regions, such as the Tacoma Narrows Bridge collapse and corrosion in marine platforms, highlight the widespread and costly consequences of concrete degradation. The manuscript underscores the need for effective prevention and mitigation strategies, emphasizing the role of advanced materials like self-healing concrete, corrosion inhibitors, and protective coatings in extending the lifespan of concrete infrastructure. Regular monitoring using non-destructive testing methods is also recommended to identify early signs of corrosion. The review concludes with recommendations for innovative solutions and broader adoption of sustainable practices to reduce the environmental and economic impacts of concrete corrosion.
