Geopolymer Concrete: A Scientometric Study on Current Trends in Scientific Production

The construction industry is among the main contributors to pollution and waste generation throughout all its stages—before, during, and after each activity. This scenario has driven the search for more sustainable materials. In this context, geopolymers have emerged as a promising alternative to Portland cement, capable of reducing the environmental footprint and enabling the production of lower-impact concretes. This study presents a scientometric analysis of recent literature on geopolymer concrete, covering the period from January 2023 to July 2025. Metadata from articles indexed in Web of Science and Scopus were extracted and processed using Bibliometrix (R-package) and VOSviewer (1.6.20). The analysis identified the most influential authors, institutions, countries, journals, and keywords in the field. The results reveal that the most cited articles focus on topics such as mechanical properties, the implementation of geopolymers in 3D printing, predictive models, and machine learning applied to performance assessment and the formulation of low-carbon concretes. Furthermore, scientific production is highly concentrated in Asia, particularly China and India, with limited international collaboration with other regions, such as Australia, Saudi Arabia, and Malaysia. In conclusion, the field remains strongly technical and application-oriented, but it requires research strategies that foster global cooperation and interdisciplinary approaches to consolidate the use of geopolymers in sustainable construction.
