On the preservation of reinforced concrete architectural masterpieces: The challenges of the <scp>REcube</scp> project

Abstract The preservation of reinforced concrete masterpieces from the 20th century poses a complex challenge. These structures often combine architectural, historical, and technological value, which standard engineering codes and conservation practices are not fully equipped to address. The Erasmus+ REcube project responded to this gap by promoting an integrated, interdisciplinary approach that brings together technical knowledge, design thinking, and heritage awareness. In parallel with ongoing developments in international codes, such as the fib Model Code 2020, REcube explored ways to translate current research into effective tools and guidelines for assessing, protecting, and reusing existing concrete structures. The project also created an educational framework involving architecture and engineering students from multiple European universities. This included a MOOC, on‐site interdisciplinary workshops, and collaborative design activities, aiming to foster critical skills for addressing real‐world conservation scenarios. This paper outlines the key elements of the REcube methodology and reflects on the educational outcomes and operational challenges encountered. Results show that hands‐on, context‐driven formats supported student engagement and interdisciplinary dialogue, while also offering a valuable testing ground for emerging technical solutions.
