← ScienceWhich consequence results when sustained high humidity weakens epoxy-bonded concrete reinforced with barium sulfate?
A)Ionic hydration compromises adhesive bonds✓
B)Covalent hydrolysis forms silanol groups
C)Hydrogen dissociation generates osmotic pressure
D)Metallic corrosion induces galvanic separation
💡 Explanation
Ionic hydration causes epoxy degradation because barium sulfate, an ionic compound, attracts water molecules, disrupting polymer crosslinking. Therefore, adhesive bonds fail as water weakens ionic attractions, rather than hydrolyzing covalent bonds or inducing corrosion.
