Which consequence results when sustained chloride exposure undermines cohesion?

A)Rebar corrosion accelerates rapidly locally
B)Concrete compressive strength transiently increases
C)Shear capacity sees marginal increase
D)The alkalinity buffers acidification effects

💡 Explanation

Chloride exposure causes the *de-passivation* of rebar because it allows oxidation to proceed rapidly; therefore rebar corrodes more locally and quickly. This occurs due to ionic interactions with the steel surface, rather than affecting surrounding concretes alkalinity or short-term strength capacities.
