Abstract: Because of the different mix design in comparison with traditional concrete and the absence of vibration, different durability characteristics might be expected for selfcompacting concrete (SCC). Indeed, the degradation mechanisms of a cementitious material are greatly influenced by the permeability of the material for potentially aggressive substances. As the pore structure might be different for SCC in comparison with traditional concrete, some changes in durability behaviour might be noticed.
This paper is first giving an overview of hydration, pore structure, air-void system and transport mechanisms of self-compacting concrete. Afterwards, available durability results are studied and summarised keeping in mind the fundamental mechanisms and driving forces.
In this way some more general view on durability of Self-Compacting Concrete is obtained.
All relevant durability issues are considered, like carbonation, chloride penetration, frost resistance, ASR, sulphate attack, thaumasite formation, and fire resistance. It is not the intention to give a review on these durability aspects for concrete in general. The aim however is to point at the specifics related to the use of SCC, e.g. due to the addition of a large amount of limestone filler, etc…
