Which risk increases substantially when post-tensioning of a concrete beam is delayed in humid conditions?

💡 Explanation

Accelerated tendon galvanic corrosion is a risk due to possible chloride penetration from the humid environment augmenting the electrochemical difference between the coated and uncoated tendon steel material because oxygen availability increases the corrosion rate. Therefore corrosion can cause the tendons to weaken, rather than shear capacity diminishing.
