“…Experiments have shown that polymer-concrete composites can absorb dynamic load energy much faster than conventional concrete. Therefore, the positive effects of synthetic fibers on the damping rate have been proven in the literature [38]. In Figure 5, when the curves and damping ratio results are compared, steeper peaks show lower damping and lower peak higher damping.…”

“…Song et al [44] investigated the Leeb hardness of sodium silicate-based concrete and regular C30 concrete and concluded that the average hardness value of regular concrete was 362 HL, and that of sodium silicate-based concrete was 405 HL. In [38] studies, Lebb hardness values for UHPCs were measured between 620-640 HL. Lebb hardness values measured for samples vary between 575-583 HL.…”

Recently, it is known that carbon fiber, which is a conductive fiber, is used in different mixture designs and developing electrically conductive cementitious materials. However, the evaluation of ferrochrome as a recycled aggregate in the mixture of these special concretes has still not been investigated. In this study, electrically conductive mortars were produced by using 100% recycled ferrochrome aggregate with a particle size of less than 1 mm as filling material and using carbon fiber (CF) in 4 different ratios, 0%, 0.5%, 0.75% and 1%. 2, 14, 28, 90 and 180 days electrical resistivity properties of the obtained samples were investigated. In addition, 28-day compressive strength, flexural strength, dynamic resonance, ultrasonic pulse velocity (UPV), Leeb hardness, scanning electron microscope (SEM) and X-Ray Diffraction (XRD) tests were performed on all samples. The obtained results were compared with the literature and it was proved that ferrochrome can be used as a reasonable aggregate in conductive mortars.

“…The addition of fibers (steel/natural/synthetic) to the cementitious mixtures improves their mechanical properties [ 24 , 25 , 26 , 27 , 28 ]. Although the role of fiber might not always involve an increase in strength, it has a considerable favorable effect on ductility, resilience to dynamic loading, and toughness [ 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. Concrete reinforcement with fibers is not a substitute for traditional steel reinforcing bars because steel bars and fibers serve distinctive, but both function in improving the concrete performance [ 36 , 37 , 38 ].…”

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.

“…This driving factor is especially powerful since global measurements of bulk attributes do not disclose the processes behind certain events. There is a need to model material characteristics on a mesoscale, as opposed to solely on a macroscale [ 26 , 27 ]. Numerous studies [ 28 , 29 , 30 ] that investigated the impact of fiber content on SFRC fracture characteristics have concluded that increasing the fiber volume content might significantly improve the pull-out strength and flexural strength.…”

A Comprehensive Analysis of the Use of SFRC in Structures and Its Current State of Development in the Construction Industry

In recent years, concrete technology has advanced, prompting engineers and researchers to adopt advanced materials to improve strength and durability. Steel-fiber-reinforced concrete (SFRC) represents the substantial modification of concrete materials to improve their structural properties, particularly their flexural and tensile strength. Whether SFRC is stronger than conventional concrete depends on a variety of variables, including the volume, size, percentage, shape, and distribution of fibers. This article provides a comprehensive discussion of the properties of SFRC, such as durability, fire resistance, and impact resistance or blast loading, as well as the application of SFRC in structural members including beams, columns, slabs, and walls. The application of steel fibers in various types of concrete, including pre-stressed, pre-cast, self-compacting, and geopolymer concrete, was also examined in this comparative analysis review, and recommendations for the future scope of SFRC were identified.
