水化阿利特的氩宽离子束切片和高分辨扫描电镜成像
Argon Broad Ion beam sectioning and high resolution scanning electron microscopy imaging of hydrated alite
摘要：
扫描电子显微镜（SEM）成像能够可视化水泥和混凝土的微米至纳米结构。一个先决条件是样品制备保留了样品的天然结构。在这项研究中，氩宽离子束（BIB）切片相比，国家的最先进的样品制备（树脂包埋，抛光）的水化阿利特。此外，它是调查，如果在BIB，样品冷却是有益的，以避免恶化的水泥水化物。目的是定量测量硬化阿利特膏体中的相和孔径分布。因此，不仅优化样品制备，而且优化成像条件进行了研究。最后，它表明，通过图像分析孔的直径为5 nm的水化阿利特膏可以定量分析。
英文摘要：
Scanning electron microscopy (SEM) imaging is able to visualize micro- to nano-structures of cement and concrete. A prerequisite is that the sample preparation preserves the native structure of the specimen. In this study, argon Broad Ion Beam (BIB) sectioning is compared to state-of-the-art sample preparation (resin embedding, polishing) for hydrated alite. Additionally, it is investigated if during BIB, sample cooling is beneficial to avoid deterioration of cement hydrates. The aim is to quantitatively measure phase and pore size distributions in hardened alite pastes. Therefore, not only optimized sample preparation but also optimized imaging conditions are investigated. Finally, it is demonstrated that by image analysis pores down to a diameter of 5 nm in hydrated alite pastes can be quantitatively analysed.
