Which outcome occurs when high humidity weakens plaster?

💡 Explanation

The outcome is ionic repulsion due to water weakening ionic bonds in calcium sulfate because water molecules reduce the electrostatic attraction via dielectric screening. This decrease in attraction reduces cohesion, therefore the material loses strength, rather than undergoing covalent hydrolysis.
