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~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.
