Which consequence resulted from poorly bonded mortar in Roman concrete?

💡 Explanation

Accelerated bio-deterioration occurs because capillary action draws moisture through the porous mortar, promoting microbial growth; Water intrusion accelerates material breakdown, therefore, compromising durability occurs rather than enhanced resistance, if properly, hydration and other binding process happened.
