摘要

Marine infrastructure withstands extreme conditions such as chloride-rich environments; however, traditional durability assessments often inadequately reflect long-term performance. This study emphasises the importance of evaluating geopolymer concrete (GPC) for maritime applications through a performance-based methodology. An extensive review of contemporary research includes transport properties, electrochemical behaviour, microstructural development, reliability modelling, and life-cycle sustainability. The investigation comprehensively analysed key features, including chloride transport, corrosion resistance, gel structure stability, and probabilistic durability indicators, through advanced characterisation and modelling techniques. Geopolymer concrete (GPC) exhibits notable durability improvements, characterised by chloride diffusion coefficients generally below 1.0 × 10⁻¹² m²/s, strength retention exceeding 90%, and reduced failure risk following extended exposure. The life-cycle evaluation of durability indicates that geopolymer concrete (GPC) exhibits a carbon footprint reduction of 40–60% compared to conventional systems. The results suggest that sustainability, durability, and reliability must be assessed together using performance-oriented, time-based criteria. This research investigates cutting-edge design approaches for assessing the service lives of marine structures using durability-reliability frameworks. Geopolymer concrete (GPC), known for its performance-driven approach, offers higher strength, greater reliability, and lower carbon emissions, with excellent performance in sustainable marine infrastructure.
