Which consequence results when mortar carbonation occurs within Inca masonry walls?

💡 Explanation

Seismic vulnerability increases during mortar carbonation of Inca masonry because calcium hydroxide reacts with atmospheric CO2 leading to calcium carbonate formation. This causes decreased mortar elasticity and cohesion; therefore the wall is less resilient during seismic events, rather than changing thermal property or the effects of aggregate or plant roots.
