Which risk increases in post-tensioned concrete beams if grout injection inadequately fills duct voids?

💡 Explanation

When duct voids remain unfilled, corrosion accelerates because moisture and chlorides can penetrate, attacking the steel tendons due to electrochemical reactions. Therefore accelerated corrosion risk increases, rather than load capacity decrease, shear increase, or ductility reduction, which depend on different structural factors.
