Impact of Sulfate Ion and Soft Grout on Post-Tensioned Concrete Bridges

Project Information

Project Abstract: 

This project is to investigate corrosion performance of post tensioning tendons caused by grout segregation especially in the form of soft grout and the role of elevated concentrations of free sulfate ions in the corrosion process in the presence of various concentrations of chloride ions.
