Abstract: 
Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) provides excellent durability qualities and performs well in hydraulic structures that are exposed to extreme environments and require resistance to impact and abrasion. The following UHPFRC projects are detailed:
- the Caderousse and Beaucaire Dams on the Rhone River, France, operated by Compagnie Nationale du Rhône (CNR): UHPFRC from Lafarge was used to repair the foundation slab of a gate bay as well as vertical walls;
- Channel-bridges over the Maurienne motorway (Alps, France): Aluminous concrete was replaced with about 648 m2 of UHPFRC from Vicat and Eiffage on a 10 % slope slab;
- the ‘Les Bois’ hydroelectric power plant in Chamonix (Alps, France), operated by Electricité de France: UHPFRC from Eiffage and Lafarge was applied between rails in the underground water intake. The water arrives directly from the glacier river of the ‘Mer de Glace’ and is extremely abrasive.
Each of the above projects is regularly exposed to severe environmental conditions and demonstrates that UHPFRC provides innovative solutions for hydraulic structures.
