← HistoryWhich outcome occurs when voids form inside the structure of Roman aqueduct concrete?
A)Increased hydrostatic pressure develops✓
B)The structure experiences resonance frequencies
C)Improved freeze-thaw weathering resistance
D)Reduced hydraulic head loss within channels
💡 Explanation
Increased hydrostatic pressure develops because voids compromise structural integrity; this triggers a stress concentration mechanism accelerating cracking, therefore weakening sections rather than uniformly resisting pressure or aiding resilience as temperature falls.
