Non-linear decay of building stones during freeze-thaw weathering processes

► 102 Samples of carbonate rocks were tested during 100 cycles of freeze-thaw. ► Decay evolution was characterized at micro/meso-scale and petrophysically. ► Ultrasonic attenuation is the most useful parameter for studying damage evolution. ► Strength, porosity and weight decrease are not useful for damage quantification. ► Standard procedures are revealed as not effective for rock durability diagnostics.
