Self-compacting　Concrete　(SCC)　has　many　good　properties　such　as　high　fluidity,　good　cohesiveness　and　resistance　to　segregation.　Therefore,　SCC　should　have　higher　durability　compared　to　ordinary　vibrated　concrete　in　theory.　At　the　same　time,　the　cementitious　materials　and　additives　used　in　SCC　are　much　more　than　that　of　used　in　ordinary　concrete,　which　will　cause　SCC　to　generate　shrinkage　cracks　easily　and　deteriorate　its　durability.　So　the　durability　of　SCC　should　be　studied　further.　In　this　paper,　C30　similar　to　C60　SCC　were　prepared,　and　then　the　permeability　and　reinforcing　bar　corrosion　of　reinforced　self-compacting　concrete　were　conducted.　The　results　show　that　the　permeability　of　SCC　is　lower　which　make　sure　the　embedded　reinforcing　bars　have　high　resistance　to　the　corrosion.
