Le Ductal, ce b\u00e9ton \u00e0 ultra hautes performances, d\u00e9velopp\u00e9 par Lafarge, utilis\u00e9 par des grands noms de l’architecture dans des chantiers embl\u00e9matiques, \u00e9tait jusqu’\u00e0 pr\u00e9sent coul\u00e9. Pour la premi\u00e8re fois, ce b\u00e9ton fibr\u00e9 fait l’objet d’un proc\u00e9d\u00e9 de projection qui augmente son caract\u00e8re ductile, autorisant ainsi des \u00e9l\u00e9ments monobloc de tr\u00e8s grande dimension (18 m\u00b2) avec des \u00e9paisseurs en partie courante de 12 mm. Ce proc\u00e9d\u00e9 permet \u00e9galement la projection de la matrice sur des parois verticales de plus d’un m\u00e8tre, permettant de s’affranchir des coffrages complexes et ainsi r\u00e9pondre \u00e0 une infinit\u00e9 de projets architecturaux. Le CSTB vient de remettre une ATEx (appr\u00e9ciation technique exp\u00e9rimentale) pour cette utilisation \u00e0 Betsinor, apr\u00e8s 3 ans de recherche et d\u00e9veloppement en partenariat avec Lafarge, et plus d’un an de travail de recherche d’approbation. L’ATEx est de type A, donc valable pour plusieurs chantiers. Le premier projet \u00e0 b\u00e9n\u00e9ficier de ce proc\u00e9d\u00e9 est le nouveau centre de formation d’EDF sur le plateau de Saclay (91) : 2 500 m2 de fa\u00e7ade vue sur 3 niveaux seront couverts de panneaux en DUCTAL projet\u00e9.<\/p>\n
