Which consequence arises when mortar carbonation weakens limestone masonry?

💡 Explanation

Carbonation increases the porosity making masonry more susceptible to water penetration; therefore, freeze-thaw weathering creates cracks from expansion and fracturing, rather than increased load bearing because compressive arch support mechanisms are weakened.
