Research
The overall goal of our research is to improve the sustainability in the production and application of mineral construction materials by examining all phases of the material lifecycle (production, hydration, and durability). To this end, we investigate the fundamental mechanisms that determine the hydration and durability of novel environmentally friendly and sustainable mineral materials. We combine various experimental methods with thermodynamic modeling. As part of the Centre for Building Materials (cbm) at TUM, we are equipped with a wide range of chemical, physical, and mechanical testing and examination methods, allowing us to study mineral construction materials from the nano to the macro scale, thus linking fundamental insights with the practical application of building materials.
The Professorship for Mineral Construction Materials is part of the cbm and consists of two research groups.
The research group „Mineral Binders and Additives“ focuses on the novel, ressource-efficient, energy-extensive binders and effective treatment processes as part of its research. Furthermore, the group's research focus is on the activation of pozzolanic additives during the early hydration stages and the clarification of chemical damage mechanisms in concretes, such as the alkali-silica reaction. In the field of material testing, approval and monitoring tests are carried out on binders and additives. As a recognized test site for ASR, we conduct ASR tests on aggregates and concrete mixtures for use in road construction, railway sleepers, and airfield pavements.
The research group „Chemistry“ serves as a link between the application-oriented research themes in engineering and fundamental research. The various cbm research groups receive support in all chemical questions, and their projects are complemented with the appropriate chemical examinations. The group's own research topics mainly concern chemical effects such as acids on concrete and the investigation of the hydration of complex composite binder systems. In this context, the application of solid-state NMR spectroscopy has developed into a key focus.
