Freeze–thaw (FT) action is a major cause of rock deterioration in alpine regions. To explore damage evolution of sandstones in cold environment, artificial FT experiments were conducted in the laboratory. Saturated and dry sandstone specimens were subjected to 0, 7, 14, and 28 FT cycles. X-ray compu...
