“…Cement-based materials are known to be brittle due to the significantly lower tensile strength compared to the compressive strength, thus causing catastrophic failures without considerable plastic strain [ 21 , 22 ]. It has been discovered that including fiber enhances the tensile strength and ductility of cement-based materials, thus preventing destructive failures [ [26] , [27] , [28] , [29] ]. The ratio of the flexural

to the compression strength

can represent the brittleness of cement-based materials; i.e., the higher

ratio is, the lower the material's brittleness becomes.…”

“…Moreover, this technique can significantly augment mechanical strength and durability compared to normal curing [ [36] , [37] , [38] ]. As the inclusion of fiber in cement-based materials can dramatically enhance these characteristics by arresting the growth and propagation of cracks [ [26] , [27] , [28] , [29] ], it is believed that MFs can affect the properties of carbonation-cured specimens by influencing the diffusion of CO 2 , though how is not well known. To rectify the scarcity of available research outcomes, the properties of nine mixes were also assessed after 28 days of carbonation curing (CC).…”

“…In addition, cement-based materials commonly experience shrinkage cracking over time, thus decreasing the durability of the structures in which they exist [ [23] , [24] , [25] ]. To overcome the weaknesses mentioned above, different types of fibers, such as steel, polypropylene, carbon, and glass, have been introduced into concrete mixes, augmenting the mechanical properties of cement-based materials [ [26] , [27] , [28] , [29] ]. It should also be noted that even if these fibers provide several advantages, they are expensive and increase the total cost of the project.…”

“…In order to suppress the pulling of steel fibers from the concrete matrix, a large number of steel fibers with various shapes and geometries are manufactured worldwide [ 56 ]. The geometry of steel fibers that have been applied in geopolymer concrete includes hooked-end steel fiber, crimped steel fiber, straight steel fiber, twisted steel fiber, corrugated steel fiber, and others [ 57 , 58 ]; the more common types of steel fibers are shown in Figure 6 .…”

Geopolymer is widely used as a supplement to cementitious composites because of its advantages of low carbon and environmental protection, and geopolymer concrete is also broadly used in practical engineering. In recent years, geopolymer concrete has attracted increasing interest owing to its superior mechanical properties, and a series of research results have been obtained. In this paper, from the preparation of geopolymer concrete, based on the characteristics that geopolymer concrete is brittle and easy to crack, the types and basic properties of fibers to enhance the toughness of concrete are analyzed, the advantages and disadvantages of different fibers used as a material to enhance the toughness of concrete are summarized, and we review the effects of type, shape, volume rate, aspect ratio, and hybrid fiber combinations on the static mechanical properties. The results indicate that fibers have significant potential to enhance the compressive strength, splitting tensile strength, flexural strength, and fracture toughness of geopolymer concrete, and the optimal fiber volume rate seems to be related to the fiber type. Whereas the effect of aspect ratio and hybrid fiber combinations on the properties of geopolymer concrete seems to be obvious. This paper reviews the influence of fiber on the basic mechanical properties of geopolymer concrete, which provides a solid foundation to promote the further development and application of the research on the toughness of fiber-reinforced geopolymer concrete and provides recommendations for future research.

This study performed a scientometric-based examination of the literature on steel fiber-reinforced concrete (SFRC) to identify its key elements. Typical review papers are limited in their capacity to link distinct segments of the literature in an organized and systematic method. The most challenging aspects of current research are knowledge mapping, co-occurrence, and co-citation. The Scopus search engine was used to search for and obtain the data required to meet the goals of the study. During the data evaluation, the relevant publication sources, keyword assessment, productive authors based on publications and citations, top papers based on citations received, and areas vigorously involved in SFRC studies were recognized. The VOSviewer software tool was used to evaluate the literature data from 9562 relevant papers, which included citation, abstract, bibliographic, keywords, funding, and other information. Furthermore, the applications and constraints related to the usage of SFRC in the construction sector were examined, as well as potential solutions to these constraints. It was determined that only 17 publication sources (journals/conferences) had published at least 100 articles on SFRC up to June 2022. Additionally, the mostly employed keywords by authors in SFRC research include steel fibers, fiber-reinforced concrete, concrete, steel fiber-reinforced concrete, and reinforced concrete. The assessment of authors revealed that 39 authors had published at least 30 articles. Moreover, China, the United States, and India were found to be the most active and participating countries based on publications on SFRC research. This study can assist academics in building collaborative initiatives and communicating new ideas and techniques because of the quantitative and graphical depiction of participating nations and researchers.
