← HistoryWhich outcome occurs during freeze-thaw cycles on poorly mortared stone structures?
A)Increased hydrostatic pressure fracturing stones✓
B)Accelerated CO2 absorption within the stone
C)Diminished seismic wave attenuation
D)Elevated thermal expansion mismatched stresses
💡 Explanation
Increased hydrostatic pressure occurs because water permeates masonry; therefore, volume expansion during freezing induces stress beyond the stone's tensile strength, rather than chemical changes or altered properties, leading to cracking.
