Some of them have broken construction speed records due to the simplification of the construction process, particularly in non-standard geometries. However, for performance and security reasons the materials used had considerable amounts of Portland cement (PC), a constituent that increases the cost and environmental impact of 3D Printable Materials (3DPM). Supplementary Cement Materials (SCM), such as fly ash, silica fume and metakaolin, have been considered a good solution to partially replace PC. This work aims to study the inclusion of limestone filler, fly ash and metakaolin as SCM in 3DPM. Firstly, a brief literature review was made to understand how these SCM can improve the materials\u2019 3DP capacity, and which methods are used to evaluate them. Based on the literature review, a laboratory methodology is proposed to assess 3DP properties, where tests such as slump and flow table are suggested. The influence of each SCM is evaluated by performing all tests on mortars with different dosages of each SCM. Finally, a mechanical extruder is used to extrude the developed mortars, which allowed us to compare the results of slump and flow table tests with the quality of extruded samples.<\/jats:p>","DOI":"10.3390\/su14073970","type":"journal-article","created":{"date-parts":[[2022,3,29]],"date-time":"2022-03-29T21:45:51Z","timestamp":1648590351000},"page":"3970","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Influence of Supplementary Cementitious Materials on Fresh Properties of 3D Printable Materials"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3359-5157","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Teixeira","sequence":"first","affiliation":[{"name":"CONSTRUCT, Faculty of Engineering (FEUP), University of Porto, 4200-465 Porto, Portugal"}]},{"given":"Cec\u00edlia Ogliari","family":"Schaefer","sequence":"additional","affiliation":[{"name":"School of Arts, Communication and Hospitality, Architecture and Urbanism, University of the Itaja\u00ed Valley, Itaja\u00ed 88302-901, SC, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6371-0179","authenticated-orcid":false,"given":"Lino","family":"Maia","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculty of Engineering (FEUP), University of Porto, 4200-465 Porto, Portugal"},{"name":"Faculty of Exact Sciences and Engineering, University of Madeira, 9020-105 Funchal, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5911-9423","authenticated-orcid":false,"given":"B\u00e1rbara","family":"Rangel","sequence":"additional","affiliation":[{"name":"CONSTRUCT, Faculty of Engineering (FEUP), University of Porto, 4200-465 Porto, Portugal"},{"name":"CEAU, Centre for Studies in Architecture and Urbanism, Faculty of Architecture (FAUP), University of Porto, 4150-564 Porto, Portugal"}]},{"given":"Rui","family":"Neto","sequence":"additional","affiliation":[{"name":"Institute of Science and Innovation in Mechanical and Industrial Engineering (INEGI)\/Faculty of Engineering (FEUP), University of Porto, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9327-9092","authenticated-orcid":false,"given":"Jorge Lino","family":"Alves","sequence":"additional","affiliation":[{"name":"Institute of Science and Innovation in Mechanical and Industrial Engineering (INEGI)\/Faculty of Engineering (FEUP), University of Porto, 4200-465 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,28]]},"reference":[{"key":"ref_1","unstructured":"(2021, July 02).
