This study compares thirteen natural and industrial samples of supplementary or emerging supplementary cementitious materials (SCMs): slag, fly ashes, pozzolan, obsidian, silica fume, and recycled glass. These materials are used or are under consideration for decarbonization in cement plants. XRF, XRD and Raman microspectroscopy were used in order to achieve a deeper understanding of the structural characterization of SCMs. The changes in position and shape of the XRD diffuse halos were compared. Raman spectroscopy was used to study the glass part of the SCM families, to better understand their structure in terms of depolymerization degree, angle, ring size and incorporations into the glass.

反应性辅助胶凝材料 (SCM) 和再生玻璃的玻璃状结构： XRD 和拉曼光谱对其表征的贡献

本研究比较了补充或新兴补充胶凝材料 (SCM) 的 13 种天然和工业样品：矿​​渣、粉煤灰、火山灰、黑曜石、硅粉和回收玻璃。这些材料已用于或正在考虑用于水泥厂的脱碳。为了更深入地了解 SCM 的结构表征，使用了 XRF、XRD 和拉曼显微光谱。比较了 XRD 扩散晕的位置和形状的变化。拉曼光谱用于研究 SCM 系列的玻璃部分，以更好地了解它们的解聚度、角度、环尺寸和玻璃中的结合情况。
