Mineral-bonded composites for enhanced structural impact safety: The vision of the DFG GRK 2250

Existing reinforced concrete structures feature, as a rule, a relatively low resistance to various sorts of impact loading, such as shock, collision, or explosion. To this aim, the primary goal of the Research Training Group (in German: Graduiertenkolleg, GRK) 2250, funded by the Deutsche Forschungsgemeinschaft (DFG), is to bring substantial improvements in the impact resistance of existing buildings by applying thin layers of strengthening material. By using innovative mineralbonded composites, public safety and reliability of vitally important existing structures and infrastructure should be significantly enhanced. The scientific basis to be developed will additionally enable to build new, impact-resistant structures economically and ecologically. The framework of the GRK 2250 as well as some achievements are herein briefly presented.
