Pioneering approaches for more environmentally friendly concrete structures - from natural fibre reinforcement to design optimization.

On May 13, 2025, the KOMMEN lecture by Prof. Dr.-Ing. Marcus Ricker entitled "Ways to a more sustainable use of concrete - progress, challenges, potentials" took place in the Doric Hall of the Department of Architecture and Civil Engineering.

In his lecture, Prof. Ricker presented promising approaches to minimizing the environmental impact of concrete structures. Topics were covered that are either currently being worked on at the Chair of Concrete Structures or have been until recently. Specifically, these are the areas of design optimization, textile reinforcement made of natural fibres, slender load-bearing structures and the application of reliability theory for a more efficient use of resources.

Prof. Ricker also emphasized the importance of committee work, as this is where future guidelines and standards are created. For this reason, he is actively involved in several working committees at DIN and the German Committee for Reinforced Concrete. Modern regulations ideally create uniform framework conditions for the development of new technologies and can therefore help to make the construction industry more sustainable in the long term.

At the end of his presentation, Prof. Ricker was optimistic: despite major challenges, it is possible to implement the transformation towards a more sustainable concrete construction method. However, this would require close cooperation between science and practice as well as the coordinated use of modern technologies and materials.

After the lecture, there was the opportunity to exchange ideas over drinks and snacks.
