Bibliometric Analysis of Zeolite in Concrete Using VOSviewer: Advancing Sustainable Construction Materials

A comprehensive bibliometric analysis of zeolite in concrete was conducted using VOSviewer software (version 1.6.21). The database was obtained from Scopus by searching for zeolite in concrete. A filter for the years 2000 to 2025 was applied. A total of 1001 documents related to zeolite concrete fulfilled the criteria and were downloaded. The co-occurrence networks and overlay technique were utilized to illustrate relationships. The publication trends, publication area, document types, and country-wise publications were considered for analysis. Also, the top universities/institutions and funding sources that supported zeolite in concrete-related research were considered. Furthermore, keyword analysis was used to find the past, current, and future research trends. The findings highlight the increasing importance of zeolite-based concrete, particularly from 2015 to 2024. Engineering accounted for the largest publication base, with 614 articles. Research articles represented the predominant document type, with a total of 664 publications. In contrast, only 40 of the 1001 articles are full-length review papers. The country-wise analysis indicates that Iran (163) and China (146) are at the top in scientific contributions. The keyword analysis indicates that most researchers focus on “Zeolite,” “Concrete,” “Compressive Strength,” and “Durability”. The bibliometric analysis further reveals a clear shift in zeolite-concrete research toward sustainability applications focused on durability, geopolymer, and self-compacting concrete. In addition, the study identifies several underexplored research themes, including shrinkage, creep, life-cycle assessment, and artificial intelligence-based mix optimization. The findings provide a research roadmap for advancing the next generation of sustainable zeolite-based concrete.
