Abstract

In offshore island-reef engineering, coral aggregate concrete (CAC) has become an important construction material because it enables the use of locally available resources and mitigates the limitations associated with (3) In offshore island-reef engineering, there is an urgent need to shift from material-level degradation mechanism studies toward condition-based, whole-life management approaches. Future research should focus on identifying key deterioration indicators associated with processes such as chloride ingress, sulfate attack, crack evolution, and protective layer degradation and establishing quantitative criteria for damage assessment and repair timing. By integrating these criteria with repair technologies suitable for marine environments, timely intervention and recovery can be achieved to improve the long-term service performance of CAC.
