← TechnologyWhich consequence results when deicing salts permeate a bridge deck?
A)Rebar corrosion accelerates significantly✓
B)Concrete compressive strength increases notably
C)Cable tension in support increases
D)Asphalt surface layer becomes more ductile
💡 Explanation
Corrosion occurs due to chloride ion diffusion, accelerating oxidation through the **electrochemical reaction**. Water and ions promote electron transfer, causing iron to oxidize, therefore the steel weakens structurally rather than remaining intact under stress with a passivated oxide layer.
