A bibliometric analysis of research on fiber reinforced geopolymer composites

To investigate and analyze the vast scientific data from the field of geopolymers, bibliometric analysis with different software is the most precise and efficient technique. In this field, the network visualization of keywords and authors of published papers is of particular significance. Therefore, the aim of this study is to present the progress and research interest in geopolymers, especially those reinforced with different types of fibers. Accordingly, the bibliometric data were retrieved from the Web of Science database and analyzed using the VOSviewer software. The data were retrieved from the database considering two sets of keywords: one analysis was performed for the most general term that describes the geopolymers field, i.e., "geopolymer"; the second analysis was performed to achieve the main objective of the study, and the terms "geopolymer and fiber" were used in the search. According to the WoS database, at the interrogation moment, the search for the term "geopolymer" shows 10.810 results from all databases indexed in WOS, while the search for the term "geopolymer fiber" will result in 1503 results. By processing these results with the VOSviewer software, different groups of keywords were obtained and their relevance was filtered based on different criteria as presented in the description of each map. Based on the data presented in this study, future research directions were presented.
