Exploring the potentials of adhesively bonded connections for CRC modularity

Robust and resource-efficient adhesive joints are key to the joining of carbon concrete components for the future. In this research project, we investigate the stress states within adhesive layers, combining experimental and numerical analyses to derive an adhesive-appropriate joint design. A special focus is placed on reversible connections that enable the reuse of carbon concrete components, making an important contribution to sustainable construction.

Project name	Exploring the potentials of adhesively bonded connections for CRC modularity
Project partner	Technische Universität Darmstadt, Institut für Stahlbau und Werkstoffmechanik, Fachgebiet Stahlbau TU Dresden RWTH Aachen
Grantor	DFG (Profect C09 of SFB TRR280)
Duration	from 2025 to 2028
Research field	M+M (E+E > Energy + Environment I+I > Information + Intelligence M+M > Matter + Materials)
Project content	The objective of this project is to examine the characteristics of bonded joints between components and cross-section parts composed of carbon-reinforced concrete. The objective is to gain a comprehensive understanding of the stress states within the bondline and to develop a suitable joint design. To this end, detailed experimental and numerical analyses will be conducted to establish principles for the design of robust and resource-efficient bonded joints. A particular focus is on debonding on demand, which is a prerequisite for the reuse of carbon-reinforced concrete components.
