INNOVACONCRETE is an innovative and ambitious project – started in January 2018 and spanning a three years period – funded by the European Union under the Horizon 2020 Programme with more than 6,8 million Euro. The University of Cadiz coordinates the project consortium composed by 29 partners of 11 different countries.This project aims at preserving concrete-based monuments, the most significant tangible Cultural Heritage in the 20th Century. To achieve this goal, it has recruited an interdisciplinary team presenting a strong scientific background in simulation techniques and nanomaterials synthesis, combined with a wide knowledge of CH conservation from Humanities disciplines and, a sound industrial perspective. Specifically, a completely innovative approach based on producing C-S-H gel, responsible for theengineering properties of cement paste in cracks of decayed concrete monument, in situ, will be developed. Complementary, these innovative solutions can be functionalised with superhydrophobicity and corrosion inhibition properties. In addition, InnovaConcrete will explore other approaches: enzymeassisted self-healing of damaged surfaces, inorganic nanotubes and atmospheric plasma device for product application. Thus, the selection includes monuments with significant numbers of visitors per year, such as the spectacular Centennial Hall building, included in the UNESCO world heritage list, Chillida sculptures and the Stadio Flaminio by Nervi. In addition, other buildings and sites that are hardly recognized by citizens as Cultural Heritage, such as Concrete Shell Structures, an important achievement of the postwar modernist movement, and War Memorial Towers, symbols of the collective identity of European citizens, Kaunas Fort, one of the first concrete buildings of the 20th C, have also been selected. Finally, theTorroja Building has been chosen as a representative model of interdisciplinary collaboration between architecture and engineering.
