This book provides a collection of recent research contributions that explore emerging materials, corrosion processes, structural pathologies, and cutting‑edge technologies aimed at improving the resilience of concrete structures. It highlights advancements in coated steel reinforcement, the durability of LC3 concrete, corrosion challenges in post‑tensioned systems, and the evolving role of GFRP materials in structural applications. It also addresses the growing integration of artificial intelligence as a powerful tool for diagnosing and rehabilitating infrastructures affected by dynamic actions such as vibrations. Organized into six chapters, this book provides a concise yet comprehensive overview of current knowledge for engineers, researchers, students, and practitioners across civil, structural, mechanical, and materials engineering. By bridging traditional durability science with innovative materials and intelligent assessment techniques, this book contributes to the ongoing development of safer, more sustainable, and longer‑lasting concrete infrastructure.
