This study combines 2D element mappings obtained by laser ablation with inductively coupled plasma mass spectrometry (LA-ICP-MS) and energy dispersive X-ray spectrometry (EDX) in the scanning electron microscope (SEM) to analyse the chemical composition of cement clinker phases. It is revealed that this approach enables to determine the major and trace element concentrations in phases like alite, belite and the interstitial phase of real Portland cement clinker. A protocol is shown how to record and subsequently register both datasets as such, that the combined analysis significantly broadens the output of the individual measurements. The low detection limits of LA-ICP-MS delivers trace element concentrations and the high spatial resolution and analytical accuracy of SEM-EDX identifies the clinker phases.

Results show that Ba, K, V, and Rb are preferentially incorporated into belite. This allows to study the influence of minor and trace elements on the stabilisation and reactivity of clinker phases.

本研究将通过激光烧蚀获得的二维元素映射与电感耦合等离子体质谱仪 (LA-ICP-MS) 和扫描电子显微镜 (SEM) 中的能量色散 X 射线光谱仪 (EDX) 相结合，分析水泥熟料相的化学成分. 结果表明，这种方法能够确定实际波特兰水泥熟料的 alite、belite 和间隙相等相中的主要和微量元素浓度。显示了如何记录并随后注册两个数据集的协议，从而使组合分析显着扩大了单个测量的输出。LA-ICP-MS 的低检测限提供痕量元素浓度，而 SEM-EDX 的高空间分辨率和分析精度可识别熟料相。

结果表明，Ba、K、V 和 Rb 优先掺入贝利特。这允许研究微量元素和微量元素对熟料相的稳定性和反应性的影响。
