We tested the efficacy of frequent diurnal freeze-thaw cycles (FT-1) and sustained freezing cycles (FT-2) on low-porosity Dachstein limestone (0.1 % porosity). For FT-1, we exposed three rock samples with different saturation regimes (30%, 70%, 100%) to 20 freeze-thaw cycles between 10 and -10°C while monitoring rock temperature and acoustic emission (AE). We scanned the rock samples using micro computational tomography (CT) before the first cycle, after 5, 10, 15 and 20 cycles. For FT-2, we exposed three rock samples with different saturation regimes (30%, 70%, 100%) to one sustained freezing cycle with 66 h freezing at -10°C while monitoring rock temperature and AE. We scanned the rock samples using micro CT before the first cycle and after the end of the experiment. The data set comprises all micro CT scans, rock temperature and AE data.
