In this study, the structural performance of the joint construction method using aluminum sprayed plate in concrete was evaluated, and the corrosion characteristics of the aluminum sprayed film in mortar was also evaluated. The corrosion rate of the aluminum sprayed plate in mortar was high in the early stage after mortar placing, but it decreased with the passage of the embedding period. This was due to the corrosion products deposited on the surface of the aluminum, which was presumably due to the suppression of especially anodic reactions. In the structural performance evaluation, we found that embedding in concrete reduced the slip strength relative to the specimen with no embedding, regardless of the period in concrete. However, there was no effect of the embedding period, and the slip strength was not continuously reduced. Furthermore, the slip strength was higher than that of the conventional blasting method for all embedding periods.
