Which risk increases significantly when improperly tensioning prestressing tendons in concrete beams?

💡 Explanation

When prestressing tendons are improperly tensioned, insufficient bonding force arises because of reduced compressive stresses. This causes sudden tendon slippage transferring all tensile force to a small concrete area resulting in debonding and explosive spalling. Therefore spalling is highest risk, rather than creep, buckling, or corrosion each having distinct required condition sets.
