L'appareil de bo\u00eete en forme de L est un dispositif d'essai rigide con\u00e7u pour \u00e9valuer le comportement d'\u00e9coulement du b\u00e9ton autopla\u00e7ant (BAP) \u00e0 travers des ouvertures \u00e9troites et des obstacles en forme d'armature dans des conditions conformes aux normes. La chambre en forme de L, \u00e9tanche et monobloc, se compose d'une colonne verticale, d'une porte coulissante \u00e0 ouverture rapide et de barres d'acier lisses plac\u00e9es le long de la section horizontale. L'appareil est fabriqu\u00e9 en acier inoxydable \u00e0 haute r\u00e9sistance, ce qui garantit l'absence de d\u00e9formation ou d'usure de la surface pendant les essais. Il se compose de deux compartiments : une chambre verticale o\u00f9 le b\u00e9ton est mis en place et un canal horizontal o\u00f9 l'\u00e9coulement se produit. Ces deux compartiments sont s\u00e9par\u00e9s par une rang\u00e9e de barres verticales \u00e0 la base. Les barres sont en acier de 16 mm de diam\u00e8tre et sont espac\u00e9es de 41 \u00b1 1 mm. Cette disposition simule la capacit\u00e9 du b\u00e9ton \u00e0 s'\u00e9couler \u00e0 travers les armatures. Pendant l'essai, le b\u00e9ton est coul\u00e9 dans la section verticale de la bo\u00eete en forme de L et nivel\u00e9. Lorsque la porte est ouverte, le b\u00e9ton s'\u00e9coule dans la section horizontale sous l'effet de son propre poids. Lorsque le bord d'attaque du b\u00e9ton s'arr\u00eate, la hauteur du b\u00e9ton \u00e0 l'entr\u00e9e et \u00e0 la sortie de la section horizontale est mesur\u00e9e. Le rapport entre ces deux hauteurs est d\u00e9fini comme la valeur L-h (H\u2082\/H\u2081) du b\u00e9ton. Ce rapport indique la capacit\u00e9 de passage du b\u00e9ton.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
