The vulnerability of concrete in marine environments causes premature failure and shortened service life, and decreases the resilience of concrete infrastructure in response to secondary hazards like earthquakes and fire. Existing literature confirms the superior performance of structural lightweight concrete using rotary-kiln produced expanded aggregates in these environments, including tidal and spray zones. Further, internal curing using fine lightweight aggregate contributes to the durability enhancement of normal weight concrete by mitigating shrinkage and early-age cracking. These contributions are manifested in the transport properties of concrete mixtures as valuable inputs for service life prediction models. This research utilizes experimental data and service life modeling outcomes to highlight the benefits of internally cured concrete in marine environments. The methodology employs a service life prediction model to perform parametric studies and render trends associated with mixture properties and climate characteristics. Results include sustainability performance measures including energy inputs and greenhouse gas emissions to assess the infrastructure. Conclusions help design and management professionals recognize and evaluate opportunities to reduce the environmental footprints of concrete materials and enhance the sustainability and resilience of marine infrastructure using sustainability rating guidelines.
