Which risk increases when improperly bonding prestressing tendons during concrete bridge construction?

💡 Explanation

When tendons are improperly bonded, local electrochemical cells form because moisture and chlorides penetrate voids created from imperfect bonding, causing galvanic corrosion of the steel tendons. Therefore pitting corrosion results, rather than creep, buckling, or spalling which require sustained loading, loss of rigidity, or freeze exposure conditions.
