Lecture title: "Löcher im Beton"
Do we have holes in concrete? “Holes“ are also denoted as “pores” by porous media scientists. The effective material properties of concrete and further porous materials strongly depend on the properties of these pores. Unfortunately, we are not able to classify the pore space as e.g. concrete is an intransparent material. Therefore, trying to answer the question about “holes in concrete” anyway, we are using X-Ray Computed Tomography, a technique widely used in medicine, to make concrete transparent and to characterize the pore space. Afterwards, high-resolution 3D CT-scans are for us the image-based sources for further investigations, i.e. multi-scale simulations for the determination of effective physical properties of porous media.
About Holger Steeb
Holger Steeb is a professor of Continuum Mechanics at the Institute of Mechanics and SC SimTech at the University of Stuttgart. His research focuses on multi-scale and multi-phase methods for materials with inherent microstructure, such as porous media. Imaging characterization methods (e.g. high-resolution X-ray tomography or microfluidics), which dissolve the pore space in porous materials and represent small-scale physical processes, form the basis for the development of powerful scale-bridging simulation methods in his group. Holger Steeb applies the developed experimental characterization methods and numerical simulation techniques to various problems in the geosciences, such as deep geothermal energy.
