This cementitious material has demonstrated promising results when applied as a binder in new concrete batches, provided it has been subjected to a previous carbonation process. One of the obstacles to the industrial application of this strategy is the long duration of the typical carbonation process, which requires from 3 to 28 days. Recently, the authors have developed a short two-hour carbonation process and thoroughly analysed it over its entire extension. In this paper, a parametric analysis of the carbonation process is performed towards CO2 uptake maximization, aiming to increase the feasibility of its short duration. CO2 uptake is evaluated using the ignition by furnace method and thermogravimetric analysis. Among the parameters considered, the initial water content and the CPP thickness present the highest impact on CO2 uptake. The investigation of different CO2 concentrations inside the carbonation chamber showed that the maximum CO2 uptake does not occur for the highest concentration value. Moreover, a minimum resident time for the forced carbonation of CPP in industrial contexts is presented, and is found to be highly dependent on the CO2 concentration. The particle size and purity degree of CPP revealed a limited influence on the CO2 uptake achieved. Additionally, this paper provides further insight into the mechanisms involved in the carbonation of mature cement paste while increasing the feasibility of our recently proposed short duration carbonation process.<\/jats:p>","DOI":"10.3390\/ma15196513","type":"journal-article","created":{"date-parts":[[2022,9,20]],"date-time":"2022-09-20T22:36:44Z","timestamp":1663713404000},"page":"6513","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Parametric Study towards Optimization of a Short Duration Carbonation Process of Recycled Cement Paste"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5751-8877","authenticated-orcid":false,"given":"Andr\u00e9","family":"Silva","sequence":"first","affiliation":[{"name":"Civil Engineering Research and Innovation for Sustainability, Department of Civil Engineering, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Avenue Rovisco Pais, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8435-9816","authenticated-orcid":false,"given":"Rita","family":"Nogueira","sequence":"additional","affiliation":[{"name":"Civil Engineering Research and Innovation for Sustainability, Department of Civil Engineering, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Avenue Rovisco Pais, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0994-4417","authenticated-orcid":false,"given":"Alexandre","family":"Bogas","sequence":"additional","affiliation":[{"name":"Civil Engineering Research and Innovation for Sustainability, Department of Civil Engineering, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Avenue Rovisco Pais, 1049-001 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0162-2456","authenticated-orcid":false,"given":"Dariusz","family":"Wawrzy\u0144czak","sequence":"additional","affiliation":[{"name":"Department of Advanced Energy Technologies, Faculty of Infrastructure and Environment, Czestochowa University of Technology, Dabrowskiego 73, 42-201 Czestochowa, Poland"}]},{"given":"Aleksandra","family":"\u015aciubid\u0142o","sequence":"additional","affiliation":[{"name":"Department of Advanced Energy Technologies, Faculty of Infrastructure and Environment, Czestochowa University of Technology, Dabrowskiego 73, 42-201 Czestochowa, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7746-7659","authenticated-orcid":false,"given":"Izabela","family":"Majchrzak-Kuc\u0119ba","sequence":"additional","affiliation":[{"name":"Department of Advanced Energy Technologies, Faculty of Infrastructure and Environment, Czestochowa University of Technology, Dabrowskiego 73, 42-201 Czestochowa, Poland"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"67","DOI":"10.1016\/j.cemconcomp.2018.08.003","article-title":"The impacts of policies to reduce CO2 emission within the concrete supply chain","volume":"101","author":"Filippo","year":"2019","journal-title":"Cem.
