This thesis contributes to the ongoing industrialization of the sector, which must be concurrent with a reduction in its environmental footprint.<\/p>\n<p>Extrusion\u2011based 3D printing is rapidly advancing in both academic and industrial fields, showcasing significant technical progress throughout the process. However, mix design strategies for materials that meet the rheological requirements of these systems are still lacking, particularly when it comes to alternative binders. Yet, one of the most promising avenues for achieving substantial decarbonization (over 30%) in 3D printing lies in optimizing mortar constituents and proportions, thus maximizing strength per unit volume of cement, knownto be the primary contributor to greenhouse gas emissions in mortars. In this context, mix design procedures tailored specifically to 3D printing must be explored, with a strong emphasis on environmental performance.<\/p>\n<p>This thesis introduces two optimization strategies for mortars with very low cement content. The first approach associates a contextualized life cycle assessment model with the prediction abilities of artificial neural networks for the multi\u2011objective optimization of a mortar containing threetypes of supplementary cementitious materials. The second approach utilizes a granular packing model to guide the design of LC3\u2011type mortars, destined for acceleration with aluminium sulfates. This provides a critical analysis of the pozzolanic contribution of calcined clay in regard to its negative effect on overall packing density across various application ranges.<\/p>\n<p>Finally, this research highlights the largely unexplored potential of ternary and quaternary binders for sustainable 3D printing.<\/p>\n<p>\n<\/div><\/div><\/div><\/div><\/div>\n<\/div><\/div><\/div><\/div><\/section>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":10,"featured_media":19549,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[266,251,293,299],"tags":[],"class_list":["post-19547","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-actualites-en","category-annonces-en","category-annonces-msa-en","category-soutenances-de-these-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/posts\/19547","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/users\/10"}],"replies":[{"embeddable":true,"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/comments?post=19547"}],"version-history":[{"count":4,"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/posts\/19547\/revisions"}],"predecessor-version":[{"id":19554,"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/posts\/19547\/revisions\/19554"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/media\/19549"}],"wp:attachment":[{"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/media?parent=19547"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/categories?post=19547"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/navier-lab.fr\/en\/wp-json\/wp\/v2\/tags?post=19547"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
