In this research, we discussed the methods to re-inject girder cable PC grout and prevent the projection of transverse prestressing steel bars. We have confirmed that satisfactory grouting characteristics can be secured by using the non-bleeding type grout with exhaust hoses. We have also confirmed that the projection of steel bars can be prevented by pasting belt steel plates and stainless meshes on concrete slab end blocks.
