CEMEX propose un nouveau b\u00e9ton isolant autopla\u00e7ant : Insularis\u00bb Xi. Il a pour avantages d’\u00eatre \u00e0 la fois structurel et isolant avec une capacit\u00e9 d’isolation thermique 4,5 fois plus importante qu’un b\u00e9ton traditionnel et 2 fois plus qu’un b\u00e9ton l\u00e9ger standard. Sa conductivit\u00e9 thermique s\u00e8che est de 0,4W\/m.K, c’est-\u00e0-dire la plus basse du march\u00e9 pour un b\u00e9ton structurel de classe de r\u00e9sistance LC25\/28. Parall\u00e8lement, CEMEX France vient de signer un protocole scientifique, technique et \u00e9conomique avec Vinci Construction France pour le d\u00e9veloppement d’un syst\u00e8me constructif aux propri\u00e9t\u00e9s isolantes, 100% b\u00e9ton. Ce syst\u00e8me associe le coulage de deux b\u00e9tons isolants : Insularis\u00bb Xi aux propri\u00e9t\u00e9s structurelles et Insularis\u00bb XXi, un b\u00e9ton l\u00e9ger 3 fois plus isolant que l’Insularis\u00bb Xi avec une conductivit\u00e9 thermique s\u00e8che de 0,13 W\/m.K. Ces deux b\u00e9tons permettent de r\u00e9aliser un mur bicouche dont les propri\u00e9t\u00e9s isolantes ont pour avantage de limiter voire de remplacer les isolants classiques utilis\u00e9s dans les voiles de b\u00e2timent tout en r\u00e9pondant \u00e0 la r\u00e9glementation thermique. Elabor\u00e9 par les \u00e9quipes du centre de recherche de Bienne en Suisse, ce nouveau proc\u00e9d\u00e9 est une premi\u00e8re pour CEMEX. Le partenariat avec Vinci Construction a pour objectif de valider cette solution constructive isolante. De son c\u00f4t\u00e9, CEMEX a engag\u00e9 une \u00e9tude de validation technique aupr\u00e8s d’un organisme ext\u00e9rieur. Vinci Construction, quant \u00e0 lui, prendra part \u00e0 cette \u00e9tude en apportant son expertise notamment sur les r\u00e8gles de mise en oeuvre, le calcul des performances thermiques et en r\u00e9alisant des chantiers pilotes sur des projets de construction.\u000b\u000bwww.cemexbetons.fr<\/span><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
