Abstract:
Pour-backs at post-tensioning (PT) tendons anchorage ends provide corrosion protection to the anchorage hardware, improving the durability of post-tensioned structures. However, the interface may serve as a pathway if deficiencies are present between the PT structure and the pour-back material, providing a route for water and other factors that could negatively affect the structure's integrity. Therefore, this research addressed the need to develop a pour-back material guidance and test methods to improve the bond at the interface.
