Effect of Voids in Grouted, Post-Tensioned Concrete Bridge Construction
Research objectives: 1. Assess environmental conditions at Post-tensioned (PT) bridge locations in Texas; 2. Identify critical environmental, void, and stress parameters affecting corrosion and tension capacity of PT strands; 3. Develop methods to detect and assess the void, water, and corrosion conditions in PT systems; 4. Assess the structural reliability of PT bridges during their service life and when exposed to various environmental and tendon conditions; 5. Identify critical material parameters affecting void fillability of PT grouts and, if needed, recommend modifications to PT grout specifications; and 6. Develop a repair grouting procedure.
