Which consequence results when rapid desiccation affects concrete?

A)Ionic bridging reduces fracture toughness.
B)Covalent polymerization strengthens cement matrix.
C)Hydrogen bonding increases material ductility.
D)Metallic bonding increases compressive strength.

💡 Explanation

Rapid desiccation causes shrinkage, leading to microcracks; therefore ionic bridging weakens the cement past a point of structural failure, rather than strengthening mechanisms or ductility caused by hydrogen or metallic bonding.
