History

Which risk increases when humidity reduces mortar efficacy?

A)Pietra dura inlay detachment
B)Seismic load collapse
C)Aqueduct water contamination
D)Foundational soil liquefaction

💡 Explanation

Decreased mortar integrity causes vulnerability; reduced bonding promotes inlay delamination through thermal stress. Therefore, detachment risk increases, rather than complete structural collapse, because loads are still distributed.
