← ScienceWhich outcome occurs when chloride ions disrupt the electrostatic balance in concrete?
A)Reinforcement bar corrosion accelerates✓
B)Alkali-silica reaction diminishes
C)Cement hydration reaction increases
D)Concrete compressive strength rises
💡 Explanation
Chloride ions promote the weakening of the passive film protecting the reinforcement bars, causing *chloride-induced corrosion*. This occurs because chloride ions penetrate pores, displacing hydroxyl ions which maintain passivity; therefore, reinforcing bars oxidize rather than remain stable.
