Bibliometric analysis on magnesium oxide as a binder in civil construction

Portland cement production requires substantial natural resources and energy and generates significant greenhouse gas emissions. As a more sustainable alternative, magnesium cement – comprising magnesium oxide (MgO) and silicon dioxide (SiO_₂) – has gained attention due to its comparable properties to traditional Portland cement and its potential to significantly reduce carbon dioxide (CO_₂) emissions. This study conducts a bibliometric analysis using data retrieved from the Web of Science digital platform. The analysis focuses on the scientific production from the 2020–2024 quinquennium in indexed journals classified in the A tier of the Qualis/CAPES system, specifically addressing the theme of magnesium oxide as a binder in civil construction. The sample data provided by the digital platform revealed the following trends during the quinquennium: (a) a decline in scientific production, expected to recover in the post-pandemic period; (b) the journal Construction and Building Materials accounted for the highest number of publications (43.75%); (c) the Journal of Hazardous Materials had the highest Journal Citation Reports (JCR) impact factor of 12.2 and is classified as A1; (d) China exhibited a significant disparity in publications, contributing 47.15%; and (e) the scientific interest in this topic underscores its potential as an open avenue for future research.
