Which risk increases when pre-stressed concrete beam tendon force is inadvertently released before concrete cures?

💡 Explanation

When pre-stressed concrete's tendons release force prematurely, catastrophic tensile cracking occurs because immature concrete lacks the compressive strength needed to withstand the pre-stress-induced tension. Therefore tensile cracking results, rather than corrosion, deflection, or shear issues which typically arise from different environmental or loading conditions after curing.
