Which consequence results when rapid desiccation occurs in freshly poured concrete containing high concentrations of calcium chloride?

A)Increased compressive strength development
B)Formation of expansive v cement phases
C)Pitting corrosion of reinforcing steel
D)Reduced susceptibility to freeze-thaw cycles

💡 Explanation

Increased chloride ion concentration because of rapid drying accelerates **electrochemical oxidation**, therefore disrupting the passive oxide layer on the steel rebar leading to corrosion, rather than strength gains as different cement additives would give.
