A method to improve the durability is investigated analytically for the case where SHCC is used as a functionally gradient repair material. The SHCC part is divided into multiple layers and the material properties of each layer are set functionally gradient. Then, it has been shownthat the time needed for corrosion initiation can become longer. Also, the influence of crack width of the SHCC part is clarified.
