Experimental data set of effects of mineral water on mechanical strength and microstructure of Portland cement

This release contains experimental data using PO42.5 Portland cement mixed with mineral water containing sulfate, magnesium and bicarbonate ions. The "XRD" section provides X-ray diffraction data for cement samples at 28 and 90 days under five experimental conditions. The "SEM" section includes scanning electron microscope images of cement samples at 28 days under the same five experimental conditions. The "TG-DTG" section explains how the TG and DTG values of the cement sample change with temperature (T) at 28 and 90 days.本数据集发布包含采用PO42.5硅酸盐水泥与含硫酸根、镁离子及碳酸氢根离子的矿泉水拌和制备的实验数据。"X射线衍射（X-ray Diffraction, XRD）"模块提供了5种实验条件下，水泥试样分别养护28天与90天时的X射线衍射数据。"扫描电子显微镜（Scanning Electron Microscope, SEM）"模块收录了相同5种实验条件下，水泥试样养护28天时的扫描电子显微镜图像。"热重-差热重（Thermogravimetry-Differential Thermogravimetry, TG-DTG）"模块阐明了水泥试样在28天与90天龄期时，其热重（Thermogravimetry, TG）与差热重（Differential Thermogravimetry, DTG）数值随温度（T）的变化规律。
