Surface spectroscopy laboratory

在手头的提案中，申请了两个密切协调和互补的测量设施(微机械站和表面光谱站)，包括必要的辅助仪器。这些仪器当前和未来研究的总体目标是调查组成硬化水泥相的矿物相(包括耐久性侵蚀引起的退化效应)或其他矿物的机械性能，将这些机械性能与这些相的矿物组成相关联，并调查环境变化对整个系统行为的影响。在与DFG的对话中，这些调查所需的必要仪器在两个不同的提案中得到应用，即建立一个微型机械站(包括一个纳米压痕、微压痕和刮擦工具测量头，全部安装在气候室中，外加一个汞渗透孔度计作为安装在通风柜中的辅助工具)和一个表面光谱分析站(由一个带有原子力显微镜模块和各种表面处理技术作为附件的共焦拉曼显微镜组成)。这种技术的结合将使人们能够更详细地了解建筑材料的微观结构。所应用的仪器将为IFB主要进行的中观和宏观研究提供重要的扩展。

Within the proposal at hand, two closely coordinated and complementary measuring facilities (micromechanical station and surface spectroscopy station) including the necessary accessory instruments are applied for. The overall goal of the current and future research with these instruments is to investigate the mechanical properties of mineral phases which constitute hardened cement phases (including degradation effects e.g. resulting from durability attack) or other minerals, to correlate these mechanical properties with the mineral composition of those phases and to investigate the influence of environmental changes on the behavior of the overall system. In dialogue with DFG, the necessary instruments for these investigations are applied for in two separate proposals, i.e. a proposal for a micromechanical station (consisting of a nanoindenter, microindenter and scratch-tool measurement head all installed in a climate chamber, plus an mercury intrusion porosimeter as accessory tool to be installed in a fume hood) and a surface spectroscopy station (consisting of a confocal Raman microscope with AFM module and various surface preparation techniques as accessory). This combination of techniques will allow for a much more detailed insight into the microstructure of building materials.The applied instruments will provide a significant extension of the predominantly meso- and macroscopic research at IfB.
