Which risk increases when post-tensioned concrete slab tendons experience grout voids after stressing?

💡 Explanation

When grout voids exist after stressing, moisture ingress occurs because the steel is no longer passivated, leading to localized corrosion exacerbated from chloride ions like from road salt. Therefore corrosion risk increases, rather than debonding, creep or shear which require different intrinsic structural material weaknesses.
