Exploring the potentials of adhesively bonded connections for CRC modularity | Funding Period 2

Subproject C09 investigates adhesive bonding techniques for components made of carbon-reinforced concrete (CRC), aiming to enable modular and demountable construction methods. The focus lies on developing joining technologies that ensure durable, mechanically robust connections while allowing for targeted disassembly in line with circular construction principles.

Polymer-based adhesives, as well as mineral-based adhesives, are analyzed with regard to their structural suitability, long-term performance, and failure behavior under mechanical loading. Within the scope of the project, the concept of debonding on demand is to be further developed, enabling reversible adhesive joints through controlled external stimuli.

The development of suitable bonding concepts is based on a combination of numerical simulations and experimental investigations. The insights gained will contribute to the design of demonstrators, which are intended to be tested under realistic conditions.
