Abstract: 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. At this moment however, it is unclear how significant these differences will be with regard to the concrete practice. A fundamental bottle neck in this discussion is the lack of fundamental insight in the transport behaviour of potentially aggressive media in SCC. This aspect, as well as the relation with the durability of SCC is studied in the Belgian research project 'Transport properties of potentially aggressive substances in self-compacting concrete and relation with durability', sponsored by the Belgian Fund for Scientific Research Flanders (F.W.O.-Vl.). The research project is a cooperation between the Magnel Laboratory for Concrete Research of Ghent University, the Catholic University of Leuven, and the Royal Military Academy of Brussels. The ongoing research project has the following main objectives: 1) theoretical and experimental study of the transport behaviour of potentially aggressive media in SCC; 2) experimental study of the durability of SCC, and theoretical correlation with the fundamental transport mechanisms. Both objectives should lead to a better and more fundamental knowledge of the durability behaviour of the new cementitious material. An overview will be given of the whole research project. Furthermore, the first results will be presented, dealing with water permeability, water absorption, gas permeability, carbonation resistance, frost and frost-thaw action, ...
