Which consequence resulted from mortar degradation in pre-modern masonry?

💡 Explanation

Decreased axial compression resistance arises from mortar degradation due to loss of cohesion (capillary action mechanism); because this reduced lateral support to masonry units directly. Therefore, structural integrity diminishes, rather than experiencing improved interlocking or changed expansive properties.
