The field of reinforced concrete (RC) structures in marine environments is fraught with challenges, primarily due to the pervasive issue of corrosion, which significantly reduces the service life of these structures. Corrosion, particularly chloride-induced, is a complex phenomenon that has been the subject of extensive research, with a focus on understanding the interplay between crack width, carbonation, and chloride ingress. Despite the development of prescriptive measures to limit crack width and the application of various corrosion inhibitors, such as amino alcohol migrating corrosion inhibitors (MCI), the problem persists. Recent studies have explored the effectiveness of MCI in mitigating concrete deterioration, the use of novel materials in high-performance concrete, and the development of user-friendly tools like "SL-Chlor" to estimate service life. However, the multifaceted nature of corrosion, influenced by factors such as freeze-thaw cycles, sustained loads, and the microstructure of protective coatings, continues to challenge the durability of RC structures. There is a need for a comprehensive understanding of the mechanisms at play and the development of more effective strategies to combat corrosion.
This Research Topic aims to advance the understanding of corrosion processes in RC structures within marine environments and to develop innovative strategies for enhancing their durability. The goal is to explore the effectiveness of current mitigation techniques, investigate the interactions between environmental factors and material properties, and ultimately, to extend the service life of RC structures with minimal maintenance and rehabilitation costs. Specific objectives include evaluating the performance of corrosion inhibitors, assessing the impact of environmental cycles on chloride ingress, and exploring the potential of novel materials and design approaches to improve resistance to corrosion.
To gather further insights in the complex interplay between environmental conditions and the durability of reinforced concrete structures, we welcome articles addressing, but not limited to, the following themes:
- The effectiveness of corrosion inhibitors and protective coatings in marine environments
- The role of crack width and carbonation in chloride-induced corrosion
- The impact of environmental cycles (e.g., freeze-thaw, dry-wet) on chloride ingress and concrete deterioration
- Advances in modeling and prediction of service life for RC structures
- The influence of novel materials and design approaches on the durability of RC structures
- The interaction between mechanical stresses and corrosion processes
- The development and validation of user-friendly tools for service life estimation
- The effects of electrodeposition and other electrochemical treatments on concrete rehabilitation
- The role of ambient humidity and moisture content in the migration of chloride ions
- The deterioration mechanisms of concrete and prestressing tendons in chloride-based industrial environments.
