Abstract: 
The current view of concrete durability is often fragmented, based on tests that subject specimens to one ageing mechanism at a time. The experimental results are often interpreted using Cartesian true or false logic. Hence, the current life-cycle analysis tools for concrete structures are myopic and do not capture the complexities of real world exposures and multi-damage mechanisms. The ongoing paradigm shift towards performance-based specifications necessitates improving the reliability of current testing standards and introducing rigorous performance-based test methods. Likewise, emerging computational artificial intelligence-based methods such as fuzzy inference systems are promising tools for modeling the durability of concrete structures under realistic environmental exposure and combined degradation mechanisms. This article reports on key findings from the experimental part of a five-year sustained effort at Western University to demystify multiple damage mechanisms on self-consolidating concrete, with a particular focus on sulfate attack.
