Steel Fiber-Reinforced Concrete: A Systematic Review of the Research Progress and Knowledge Mapping

Abstract

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.

A Review on Fresh, Hardened, and Microstructural Properties of Fibre-Reinforced Geopolymer Concrete

“…According to [ 117 ], strength ratings for engineered cementitious composite (ECC) without slag were much lower than those for slag tensile ECC (5.2 MPa) [ 118 ]. Hardened concrete properties are explained in Table 4 [ 16 , 44 , 56 , 95 ]. Figure 7 represents flexural strength [ 10 , 89 , 115 ].…”

“…A decrease in the size of depressions in these occurrences might be the source of the lower water absorption measurement. The porosity of the saturated example is used to determine how much water would be absorbed [ 56 , 96 , 139 ]. Figure 14 shows the moisture content [ 10 ].…”

“…For specific uses, the American Standard’s Testing of Materials A820-16 lists five varieties of fibre i.e., steel, as follows: 1. twisted or smooth cold-drawn wire bits; 2. distorted or smooth sheets cut; 3. softened and separated; 4. factory cut; and 5. changed wire steel fibre. Due to the tiny size of these steel fibres, cement scatters them haphazardly [ 56 , 57 ]. Steel fibres may have a wide range of stiffness and extreme extensions between 0.5 and 3.5% and 310 to 2850 MPa, respectively, depending on the material kind and production measure [ 58 , 59 ].…”

Dynamic Splitting Performance and Energy Dissipation of Fiber-Reinforced Concrete under Impact Loading

“…The research on fiber-reinforced concrete began in the early 20th century, with steel fiber-reinforced concrete developing the fastest. Steel fiber-reinforced concrete has been widely used in various fields, including bridges, tunnel linings, road surfaces, and precast components [7]. Previous studies have shown that, during the concrete curing process, steel fibers can effectively reduce concrete shrinkage and the number of cracks, while enhancing strength and ductility [8,9].…”

Study on the Influence of Steel Fiber Distribution on the Mechanical Properties of Perfobond Leiste (PBL) Shear Connectors

“…However, when PBL shear connectors are used to connect steel-concrete composite beams, premature failure of the concrete often occurs, resulting in the inability to fully exert the shear performance of the PBL shear connectors. If steel fibers with strong tensile strength are added to concrete to form Steel Fiber-Reinforced Concrete (SFRC), the mechanical properties of concrete will be greatly improved [11][12][13][14]. The improvement of concrete performance can bring out the shear resistance of PBL shear connectors, which can significantly improve the bearing capacity of steel-concrete composite beams [15].…”
