Which outcome resulted when mortar expansion exceeded the tensile strength in historical masonry domes?

💡 Explanation

Increased hoop stress arises because thermal volume expansion applied Radial pressure exceeds tensile tolerance, concentrating at joints via stress accumulation; therefore, the dome cracks and may collapse completely, rather than keystone displacement or corrosion.
