Extending the service life of reinforced concrete (RC) structures is paramount for sustainable infrastructure development, reducing environmental impact and minimizing resource consumption. This research investigates the degradation mechanisms of RC specimens exposed to chloride-induced corrosion, utilizing accelerated testing with impressed currents (50, 100, and 200 µA/cm2). By combining experimental measurements of corrosion product thickness and crack characteristics with numerical modeling, we aim to provide a comprehensive understanding of the degradation process. The validated numerical model will contribute to the development of predictive tools for assessing and enhancing the long-term performance of RC structures, thus promoting more sustainable construction practices.

摘要

Extending the service life of reinforced concrete (RC) structures is paramount for sustainable infrastructure development, reducing environmental impact and minimizing resource consumption. This research investigates the degradation mechanisms of RC specimens exposed to chloride-induced corrosion, utilizing accelerated testing with impressed currents (50, 100, and 200 µA/cm2). By combining experimental measurements of corrosion product thickness and crack characteristics with numerical modeling, we aim to provide a comprehensive understanding of the degradation process. The validated numerical model will contribute to the development of predictive tools for assessing and enhancing the long-term performance of RC structures, thus promoting more sustainable construction practices.
