Resistance to the frost damage, which is caused by the expansion of water in the pores during the liquid-to-solid phase transition, is one of the essential parameters in designing building ceramics. In this study, the thermal and acoustic emission analyses were used to asses the damage induced during the freeze-thaw cycling of water-saturated illite-based ceramics with varying porosity. During thermal cycling, water in the pores becomes supercooled, with the liquid-to-solid transition temperature of -10 °C. It was revealed that with increasing porosity the formation of microcracks becomes more pronounced. Early freeze-thaw cycles do not lead to a significant microcracking; on the other hand, the formation of microcracks is most active around the 50th cycle.
