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.

为探究饱和度对萨沃尼埃石灰岩的影响，对八个圆柱形石灰岩样本进行了总计六小时的冻融循环实验。通过置于每个圆柱顶部平坦表面的LVDT（线性变量差动变压器）来监测应变。同时，使用K型热电偶测量样本内部（T in）和表面（T out）的温度。样本高度为38毫米，直径为20毫米。在样本内部钻了一个10毫米深的孔，以便监测内部温度。每个样本的水饱和度不同，这在其不同工作表的标题中有所体现。样本1至6的水饱和度从样本1的50%开始，每样本增加10%，直至样本6达到100%的饱和度。这些样本通过在真空条件下完全饱和并在适当重量下进行干燥来实现饱和。样本7和8通过在大气条件下吸水48小时来实现饱和，这两个样本的饱和度均为48%。随后，样本用铝箔和塑料胶带密封，以防止蒸发，并在4°C下储存24小时。在将样本放入气候测试室之前，将圆柱的顶部和底部从密封中剥离，并通过将其压在干燥布上5分钟以及吹风2分钟进行干燥，以防止冻融循环中冰挤压对LVDT产生影响。最后，样本经历了冻融循环。在10°C下保持半小时后，温度下降至-15°C，保持半小时后再次上升1.5小时至10°C，然后在此温度下保持恒定两小时。原始测量数据包括时间、长度变化（以微米为单位）和两个位置的温度。将长度变化除以原始长度，将长度变化转换为应变，这里的应变值以m/m表示。
