Title (EN) MULTILAYER CEMENTITIOUS STRUCTURE
(FR) STRUCTURE MULTICOUCHE A BASE DE CIMENT
Abstract: front page image
(EN)The multilayer structure disclosed comprises an upper layer and a lower layer both made of a cementitious matrix. An intermediate layer made of a non-woven fibrous material and filled with a non-cementitious filling material is sandwiched between the upper layer and lower layer. The structure may advantageously comprise a plurality of intermediate layers included in a cementitious matrix. Among other things, adding a product inside the fibrous layer may reduce the weight of the structure and avoid contact between the different cement layers, thereby providing numerous advantages.
(FR)L'invention porte sur une structure multicouche comportant une couche supérieure et une couche inférieure comprenant chacune une matrice à base de ciment, et entre lesquelles est disposée une couche intermédiaire constitué d'un matériau fibreux non tissé remplie d'un matériau de remplissage autre que du ciment. Ladite structure peut également comporter plusieurs couches intermédiaires noyées dans une matrice de ciment. L'adjonction d'un produit dans la couche fibreuse peut réduire le poids de la structure et supprimer le contact entre les différentes couches de ciment, ce qui présente de multiples avantages.
