On December 17, 2025, shortly before the Christmas break, the initial project meeting with our project partners from the Department of Construction Materials and Construction Chemistry at the University of Kassel took place at the Chair of Casting Technology at FAU to launch the DFG-funded research project “UHPC as a molding material” for the development of a mineral-bound and reusable molding material for the casting of aluminum components. The project is supervised by Mr. Marco Pohl on behalf of FAU and by Ms. Janna Link on behalf of the University of Kassel.
The project focuses on the use of ultra-high-performance concrete (UHPC) and alkali-activated binders to create reusable permanent molds for light metal casting, thereby specifically reducing reactivity and thermal conductivity compared to metal molds. In addition to optimizing thermal and mechanical properties, different aggregates and fiber additives are being investigated to further increase the durability of the mold materials. In addition, experimental studies and numerical simulations provide a basis for understanding mold filling, stress distribution, and the service life of concrete molds, as well as the influence on the microstructure and mechanical properties of selected aluminum alloys.
In a constructive atmosphere, the first steps of the joint research project were planned in detail and the course was set for successful cooperation. Both partners engaged in intensive discussions about the upcoming work packages, milestones, and the distribution of tasks.
We look forward to working with the University of Kassel and are excited about the upcoming project phases in the new year!
