The following days at the Politecnico di Milano campus in Lecco were dedicated to a broad range of scientific contributions. Keynote lectures were delivered by Prof. Marco di Prisco, Prof. Matteo Colombo, and Prof. Liberato Ferrara, addressing topics such as high-performance fiber-reinforced concrete under high strain rates and elevated temperatures, shock tube testing under blast and fire loads, and the role of advanced cementitious composites in sustainable and resilient construction. In addition, GRK doctoral researchers presented their ongoing work, covering multiscale simulations, impact-resistant strengthening strategies, automated reinforcement concepts, sustainability assessments, and the application of data-driven and AI-based methods in material and structural design.
