Title (EN) METHOD OF MANUFACTURING A CONCRETE ELEMENT
(FR) PROCÉDÉ DE FABRICATION D'UN ÉLÉMENT EN BÉTON
Abstract:
(EN) In a method of manufacturing a concrete element having a functional layer, a rear side of the functional layer being bonded to the concrete element by means of an adhesive, the roughness of the rear side of the functional layer is increased by means of sand blasting, wherein the sand blasting is carried out for obtaining a surface roughness Ra of the rear side of the functional layer of between 1.5μm and 6μm.
(FR) L'invention concerne un procédé de fabrication d'un élément en béton comportant une couche fonctionnelle, ledit procédé consistant à lier une face arrière de la couche fonctionnelle à l'élément en béton au moyen d'un adhésif; et à accroître la rugosité de la face arrière de la couche fonctionnelle au moyen d'un sablage, le sablage étant réalisé afin que la rugosité de surface Ra de la face arrière de la couche fonctionnelle soit comprise entre 1,5 µm et 6 µm.
