Which outcome occurs when poorly-fired Roman bricks experience high moisture?

💡 Explanation

Calcium carbonate leaching increases within the brick due to accelerated *dissolution*, weakening structural integrity because unstable calcium compounds wash away; therefore, structural failure is more rapid, rather than the pozzolanic or boundary hardening pathways.
