This work aims to develop a methodology for the formulation of printable cement mortars incorporating industrial waste and by-products. The formulation methodology will be developed by optimising the two phases of the material separately. As a first step, starting from a printable mortar of known composition, the binder composition will be optimised to minimise portland cement content in order to reduce the cost and environmental impact of the binder. The influence of increasing levels of mineral additions and the addition of different adjuvants on the rheological behaviour of the interstitial fluid will be studied. In a second step, natural sand will be replaced by recycled sand. Consideration will be given to water absorption from recycled sands in order to control the amount of effective water. A methodology will be proposed to accurately characterise the properties of the sand and to assess the amount of effective water in a fresh mortar, taking into account the initial moisture status of the sand and the exchange of water with the dough. All this work will lead to the development of a formulation methodology to optimise the cost and environmental impact of cement inks. The formulated materials will be developed in the laboratory and then printed on a large scale to validate the relevance of the compositions. (English) | |||||||||||||||

Ce travail vise à développer une méthodologie de formulation des mortiers cimentaires imprimables incorporant des déchets et des sous-produits industriels. La méthodologie de formulation sera élaborée en optimisant séparément les deux phases du matériau. Dans un premier temps, en partant d’un mortier imprimable de composition connue, la composition du liant sera optimisée afin de réduire le plus possible la teneur en ciment portland en vue de diminuer le coût et l’impact environnemental du liant. L’influence de teneurs croissantes en additions minérales et de l’ajout de différents adjuvants sur le comportement rhéologique du fluide interstitiel sera étudiée. Dans un second temps, le sable naturel sera remplacée par un sable recyclé. On cherchera à prendre en compte l’absorption d’eau des sables recyclés afin de maîtriser la quantité d’eau efficace. Une méthodologie sera proposée pour caractériser précisément les propriétés du sable et pour évaluer la quantité d’eau efficace dans un mortier frais en tenant compte de l’état d’humidité initial du sable et des échanges d’eau avec la pâte. L’ensemble de ces travaux aboutira à l’élaboration d’une méthodologie de formulation permettant d’optimiser le coût et l’impact environnemental des encres cimentaires. Les matériaux formulés seront élaborés au laboratoire puis imprimés à grande échelle afin de valider la pertinence des compositions. (French)
