Which failure increases when de-icing salt contaminates steel reinforcement?

A)Acceleration of galvanic corrosion
B)Increased fatigue crack propagation
C)Reduced coefficient of thermal expansion
D)Decreased ultimate tensile strength

💡 Explanation

Electrolyte penetration enables increased galvanic corrosion because chloride ions enhance electron transfer between steel and other metals. This enables degradation, therefore increased galvanic corrosion occurs, rather than fatigue or tensile strength reduction, which require different failure mechanisms.
