With increasing freeze-thaw cycles, peak strength and secant modulus decrease, while mesopore and macropore porosities increase.
The study utilized freeze-thaw cycle tests, NMR measurements, and uniaxial compression tests on sandstone.
A degradation model based on mesopore porosity effectively predicts peak strength changes under freeze-thaw conditions.
Stronger connections between mesopores enhance compaction in stress-strain responses, affecting mechanical stability.
