Abstract:

This summary report explains corrosion control methods, including using flexible fillers such as petroleum-based microcrystalline wax to replace cementitious grout—an impregnation method using a silicon polymer-based corrosion inhibitor that impregnates the grout to form a barrier to moisture and oxygen upon a pressure-driven injection process—and electrically isolating tendons from surroundings and monitoring their in-service condition. These methods and ongoing efforts are encouraging developments for constructing more durable PT bridges. More time is needed to uncover pros and cons due to the limited experience with the new methods, but the bridge community has been moving forward in a positive direction.
