There were issues with the printing process when manufacturing 3D-Printed Concrete (3DPC) mixes, such as poor extrusion and buildability issues. This study investigates the use of Viscosity Modifying Agents (VMAs) in 3DPC to improve printability as well as structural integrity. VMAs, known for their capacity to change the rheological properties of concrete mixtures, are used selectively to optimise the material\u2019s flow behaviour throughout the 3D printing process. The study compares the effect of VMA concentrations on the workability and buildability properties of 3DPC mixtures. Comparative examinations of VMA-enhanced and traditional 3DPC specimens indicate that an optimised VMA dose improves structural performance. The findings of this study hold significant relevance for the advancement of 3D printing technology in construction, offering a more nuanced understanding of the role of VMAs in optimising concrete mixtures for additive manufacturing.<\/jats:p>","DOI":"10.1088\/1742-6596\/2779\/1\/012087","type":"journal-article","created":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T12:39:18Z","timestamp":1723207158000},"page":"012087","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["An
