An Overview of the Research Trends on Fiber-Reinforced Shotcrete for Construction Applications

Abstract

Abstract Research on fiber-reinforced shotcrete (FRS) for rock supports in tunneling and mining is increasing. This study used a novel approach based on scientometric analysis of FRS's bibliographic data to determine its essential components. The potential of manual review articles to link together previously isolated areas of the literature is limited. Knowledge mapping, co-citations, and co-occurrence analysis are the most challenging parts of current research. The information needed to complete the study was retrieved from the Scopus search engine. Important publishing sources, keyword analysis, writers that have the most contribution in terms of citations and publications, the most-cited articles, and the regions most actively engaged in FRS research were identified throughout the data review process. Moreover, the need for FRS and the major constraints associated with their usage were discussed. In addition to its applications in tunneling and mining, FRS can also be used for refractory linings, soil stabilization, structural restorations, and the construction of river barriers, swimming pools, shell structures, domes, and even buildings. The key barriers to employing FRS are the corrosion of fibers, high expense, and uniform fiber dispersion. Using recycled fibers, particularly from discarded tires, coating fibers with zinc/brass/copper, and employing the layer procedure, on the other hand, are superior approaches to addressing these issues. Moreover, with increased concerns about the sustainability of construction materials, efforts need to be carried out for the creation of sustainable FRS by using waste materials. The scientific description and quantitative assessment of regions and scientists might help academics build collaborative projects and disseminate new ideas and methods.
