Abstract	In order to find new application fields for either fine materials coming from building demolition or industrial byproducts, some mortars, in which fine recycled materials, obtained from a plant where rubble from building demolition are ground, are substituted to natural sand, were tested.Moreover, mortars containing either fly ash or ground brick powder as partial cement replacement were studied.Based on characterization results and performance evaluations, recycled-aggregate mortar seems to be superior in terms of mortar-brick bond strength, mainly because of its rheological properties.In addition, the use of fine recycled aggregate instead of natural sand is in accordance with the sustainable development concept, with recycling and reuse of building rubble playing a key role in meeting the need to complete the building life cycle.En vue de trouver de nouveaux domaines d’application pour les déchets de démolition ou pour quelques sous-produits industriels, des mortiers ont été produits. C’est dans ceux-ci que, par rapport à un mortier traditionnel à base de ciment, on a étudié le remplacement du sable naturel par la fraction fine recyclée obtenue d’une installation de recyclage, dans laquelle les déchets de démolition sont concassés.En outre, on a étudié des mortiers contenant soit des cendres volantes, soit de la poudre de briques concassées au lieu du ciment. En les comparant selon les résultats de la caractérisation et selon l’évaluation des performances, les mortiers avec granulats recyclés semblent les meilleurs aux termes de la tension d’adhérence entre le mortier et la brique, due à ses propriétés rhéologiques.De plus, l’usage de la fraction fine des granulats recyclés au lieu du sable naturel correspond à la notion du développement soutenable et le recyclage et le réemploi des déchets de démolition jouent un rôle clé dans la fermeture du cycle de vie des bâtiments.
