Data for: The role of ink-bottle pores in freeze-thaw damage of oolithic limestone

To investigate the impact of the saturation degree on Savonnières limestone, a freeze-thaw cycle of a total of six hours was performed on eight cylindrical limestone samples. The strain was monitored by an LVDT placed at the top flat surface of each cylinder. The temperature was also measured both inside (T in) and at the surface (T out) of the samples by K-type thermocouples. The samples were 38 mm in height with a diameter of 20 mm. A hole of 10 mm deep was drilled to be able to monitor the inner temperature.
Each sample had a different degree of water saturation. This is indicated in the titles of the different worksheets. Samples 1 to 6 had a water saturation degree starting from 50 % at sample 1 and rising with 10 % for every sample until 100 % saturation was reached in sample 6. These samples were saturated by fully saturating them in vacuum conditions and subsequent drying until appropriate weight was reached. Samples 7 and 8 were water saturated by imbibition under atmospherical conditions for 48 hours. Both of these samples reached 48 % saturation.
The samples were subsequently sealed with aluminum foil and plastic tape to prevent evaporation and they were stored for 24 hours at 4 °C. Before they were put into the climate test chamber, the top and bottom part of the cylinders were stripped from their seal and dried by pressing them onto a dry cloth for 5 minutes and by blowing air onto them for 2 minutes. This action prevents influence of ice extrusion onto the LVDT during the freeze-thaw cycle.
Finally, the samples were subjected to a freeze-thaw cycle. After half an hour at 10 °C, the temperature decreased for 1.5 hours towards -15 °C. There it remains for half an hour to rise again for 1.5 hours to 10 °C. Here the temperature is then kept constant at 10 °C for two hours.
The raw measurements are time, length change in µm and temperature at two locations. The length change is then converted to strain by dividing the length change by the original length. The strain values here are given in m/m.

为探究饱和程度对萨沃尼耶尔灰岩（Savonnières limestone）的影响，研究人员对8个圆柱形灰岩试样开展了总时长为6小时的冻融循环试验。采用安装于每个试样顶面的线性可变差动变压器（Linear Variable Differential Transformer, LVDT）监测应变变化。通过K型热电偶分别测量试样内部（T_in）与表面（T_out）的温度。试样尺寸为高度38 mm、直径20 mm，钻有10 mm深的孔洞以实现内部温度监测。
每个试样的含水饱和程度各不相同，该参数在不同工作表的标题中均有标注。试样1至6的含水饱和度从试样1的50%开始，每块试样依次递增10%，直至试样6达到100%饱和。此类试样通过真空环境下饱和后，再干燥至达到指定重量以完成饱和调控。试样7与8则采用常压下吸水饱和的方式，持续48小时，二者最终均达到48%的饱和度。
随后，试样用铝箔与塑料胶带密封以防止水分蒸发，并在4 ℃环境下静置储存24小时。将试样放入气候试验箱前，需剥离圆柱两端的密封材料，通过将其按压在干布上5分钟、并以气流吹拂2分钟的方式进行干燥，此举可避免冻融循环过程中冰胀对LVDT测量造成干扰。
最后，对试样开展冻融循环试验。试验温控流程为：先在10 ℃下保持30分钟，随后在1.5小时内将温度降至-15 ℃，并在此温度下维持30分钟，再经1.5小时回升至10 ℃，随后在10 ℃下恒温保持2小时。
原始测量数据包含时间、以微米（µm）为单位的长度变化量，以及两处监测位置的温度数据。随后通过将长度变化量除以原始长度，将其转换为应变，本次试验的应变值单位为m/m。
