Increasing the Corrosion Resistance of Marine Reinforced Concrete Structures

Increasing the Corrosion Resistance of Marine Reinforced Concrete Structures

The field of reinforced concrete (RC) structures in marine environments is fraught with challenges, primarily due to the widespread problem of corrosion that significantly reduces the service life of these structures. Corrosion, particularly chloride-induced, is a complex phenomenon that has been the subject of extensive research, focusing on understanding the interaction 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 investigated the effectiveness of MCI in reducing concrete deterioration, the use of new materials in high-performance concrete and the development of user-friendly tools such as “SL-Chlor” to predict 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 in marine environments and to develop innovative strategies to increase their durability. The aim is to explore the effectiveness of existing mitigation techniques, investigate interactions between environmental factors and material properties, and ultimately 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 new materials and design approaches to increase resistance to corrosion.

To learn more about the complex interaction between environmental conditions and the durability of reinforced concrete structures, we welcome articles addressing, but not limited to, the following themes:

– Effectiveness of corrosion inhibitors and protective coatings in marine environments

– The role of crack width and carbonation in chloride-induced corrosion

– Effect of environmental cycles (e.g. freeze-thaw, dry-wet) on chloride intrusion and concrete deterioration

– Advances in modelling and prediction of service life of RC structures

– Impact of new materials and design approaches on the durability of RC structures

– Interaction between mechanical stresses and corrosion processes

– Development and validation of user-friendly tools for service life estimation

– Effects of electroplating and other electrochemical treatments on concrete rehabilitation

– The role of ambient humidity and moisture content in the migration of chloride ions

– Deterioration mechanisms of concrete and prestressed beams in chloride-based industrial environments.


Keywords: Marine RC Structures, Chloride Induced Corrosion, Freeze-Thaw, RC Service Life, Corrosion Inhibitors, Environmental Factors


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statement. Frontiers reserves the right to direct an out-of-scope manuscript to a more appropriate section or journal at any stage of peer review.
