X-ray tomography datasets associated with the article "Moisture content impact on the dimensional and mechanical behavior of binders based on MgO and hydromagnesite or nesquehonite"

This repository provides the X-ray tomography datasets shown and discussed in the article "Moisture content impact on the dimensional and mechanical behavior of binders based on MgO and hydromagnesite or nesquehonite" by V. Hallet, M. Griffa, M. Wyrzykowski, F. Winnefeld, B. Lothenbach, submitted to the journal Materials and Structures. Each dataset consists of a .zip file, which contains a stack of 2D TIFF image files. Such files are the vertical cross-sections (aka tomographic slices) of the tomographed volume of a single sample. The following tomograms are available in this repository: MHY_80_20_wb0.65_36RH_Full_SlicesX.7z: full tomogram of a region of interest (ROI) of a mortar sample cast with hydromagnesite (Hy) and continuously cured at 36% relative humidity (RH), measured at 183 days of curing; MHY_80_20_wb0.65_36RH_Local_SlicesX.7z: local tomogram of the same mortar sample mentioned above: MNQ_80_20_wb0.65_36RH_Full_SlicesX.7z: full tomogram of a region of interest (ROI) of a mortar sample cast with nesquehonite (Nq) and continuously cured at 36% relative humidity (RH), measured at 183 days of curing; MNQ_80_20_wb0.65_36RH_Local_SlicesX.7z: local tomogram of the same sample mentioned at the preceding point. Any tomogram can be visually inspected by importing it, e.g., as an image sequence in ImageJ/Fiji (File --> Import --> Image Sequence ... menu followed by selecting the folder containing the stack of slices).本仓库提供了V. Hallet、M. Griffa、M. Wyrzykowski、F. Winnefeld与B. Lothenbach提交至期刊《Materials and Structures》的论文《含水率（Moisture Content）对氧化镁（Magnesium Oxide, MgO）基水菱镁矿（hydromagnesite, Hy）或纤菱镁矿（nesquehonite, Nq）胶凝材料尺寸与力学性能的影响》中展示并讨论的X射线断层扫描（X-ray Tomography）数据集。 每个数据集均为.zip格式压缩包，内含一系列二维TIFF（Tagged Image File Format）图像文件，此类文件对应单个试样断层扫描体积的垂直截面（亦称断层切片）。 本仓库提供以下断层扫描数据集： MHY_80_20_wb0.65_36RH_Full_SlicesX.7z：以水菱镁矿（hydromagnesite, Hy）为胶凝材料浇筑的砂浆试样，在36%相对湿度（Relative Humidity, RH）下持续养护至183天时，其感兴趣区域（Region of Interest, ROI）的完整断层扫描影像； MHY_80_20_wb0.65_36RH_Local_SlicesX.7z：上述砂浆试样的局部断层扫描影像； MNQ_80_20_wb0.65_36RH_Full_SlicesX.7z：以纤菱镁矿（nesquehonite, Nq）为胶凝材料浇筑的砂浆试样，在36%相对湿度（RH）下持续养护至183天时，其感兴趣区域（ROI）的完整断层扫描影像； MNQ_80_20_wb0.65_36RH_Local_SlicesX.7z：前述试样的局部断层扫描影像。 用户可通过导入图像序列的方式可视化查看任意断层扫描影像，例如在ImageJ/Fiji软件中，依次点击File --> Import --> Image Sequence ...菜单，随后选择包含切片堆栈的文件夹即可。
