Practical durability requirementsfor self-compacting concrete

RILEM Technical Committee 205-DSC “Durability of SCC”

This paper is first giving an overview of hydration, pore structure, and transport mechanisms of self-compacting concrete (SCC). Afterwards, available durability results are summarised keeping in mind the fundamental mechanisms and driving forces. Furthermore, the applicability to SCC of the durability requirements of the European Standard EN 206-1 is evaluated for the case of carbonation and chloride penetration. As some general and practical conclusion, it can be mentioned that the durability of self-compacting concrete is at least as good as the durability of traditional concrete with similar water/cement ratio and cement content. However, when the comparison is made based on the concrete strength, self-compacting concrete sometimes might show a somewhat inferior durability.
