Which structural weakness arises when insufficient concrete cover exists around rebar?

💡 Explanation

Insufficient concrete cover causes accelerated rebar corrosion via **electrochemical oxidation** because moisture and chlorides permeate the concrete, leading to oxidation; therefore, corrosion occurs, rather than solely reducing shear capacity or spalling.
