Chloride transport and the resulting corrosion of steel ...

2015-12-18  Relationship between the chloride diffusivity and the steel corrosion rate. It was expected that corrosion rate of the embedded steel bars would decrease with the reduction of chloride diffusivity. However, such correlation does not exist for the AAS concretes, as shown in Fig. 13. The possible reasons for the lack of any correlation are as follows: (1) in addition to chloride diffusivity, corrosion rate of the embedded steel
