Which structural consequence results when significant quantities of calcium oxide absorb atmospheric moisture?

💡 Explanation

Exothermic hydration causes swelling because CaO reacts with water in the air to form calcium hydroxide, increasing volume. This is significant expansion, therefore structural stress results, rather than compression or reduced spacing, different reactions happen under dry conditions.
