Abstract:
Although computer models for predicting the service life of reinforced concrete exposed to chlorides have been developed and enhanced during the past 15 years, there are many real-world considerations that complicate accurate and representative modeling of field structures. Recent advances in both concrete-specific models and general-purpose modeling platforms are permitting detailed investigations of the influences of many of these parameters. The article reviews these real-world considerations and provides some examples of how they are being addressed via advanced modeling capabilities.
