“…It was discovered during the experiment that the binding strength initially reduced and then grew, and authors also provided projected bond strength formulae. Nelly Majain (11)(2020) conducted an experiment on the pull test of 12mm, 16mm, and 20mm bars embedded in a 200mm cube with steel fibres. Adnan Al-Sibahy et al (14)(2020) investigated bond strength degradation caused by corrosion of steel bars implanted in the SCC, as well as variations in bond strength behaviour.…”

This article describes experimental research of the interfacial adhesion of triple blended steel fibre self-compacting concrete (TBSFSCC) and it varies depending on the percentage of steel fibre. In self-compacting concrete, mineral admixtures such as condensed silica fume and flyash are utilised as supplementary cementitious materials (SCMs).the percentage of replacement of cement by condensed silica fume at 10 where as flyash at 20 respectively, to meet the SCC criteria stipulated by ACI. The embedment length of a steel bar with a diameter of 12mm was chosen to be 100mm in all of the standard specimens. Fe-415 steel rod is used in this research. The pull-out test in the universal testing machine is used to evaluate the bond strength of this triple blended Self-Compacting Concrete (TBSCC). Ordinary steel fibres are then added to the concrete volume at various percentages, such as 0.2, 0.4, 0.6, and 0.8. The bond strength, slip, and the method of failure of each rebar were all noted in the test results. The comparison of these results clearly shows that the percentage of steel fibre contributes to the TBSCC bond strength, and conclusions are generated.

“…Majain et al [ 143 ] investigated nine 200 × 200 × 200 mm SCC cubes containing 3.5 cm long hooked-end steel fibers with an aspect ratio of 63.6 and ribbed bars with diameters of 12, 16, and 20 mm using a direct pull-out test to assess the concrete bonding behavior. The authors observed outstanding outcomes in terms of enhances tensile and compressive strength and improved bonding.…”

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.

Ioan Pop et al [12] investigated the bond strength of SCC and compared the results to those of vibrated cement concrete (VCC), concluding that SCC had a stronger bond.…”

This article describes experimental research of the interfacial adhesion of triple blended steel fibred self-compacting concrete (TBSFSCC) and it varies depending on the percentage of steel fiber. In self-compacting concrete, mineral admixtures such as condensed silica fume and fly ash are utilized as supplementary cementitious materials (SCMs). Condensed silica fume can replace 10 percent of the cement and fly ash can replace 20 percent of the cement to fulfill ACI's SCC guidelines. The embedment length of a steel bar with a diameter of 12mm was chosen to be 100mm in all the standard specimens. Fe-415 steel rod is used in this research. The pull-out test in the universal testing machine is used to evaluate the bond strength of this triple blended Self-Compacting Concrete (TBSCC). Ordinary steel fibers are then added to the concrete volume at various percentages, such as 0.2, 0.4, 0.6, and 0.8. The bond strength, slip, and the method of failure of each rebar were all noted in the test results. The comparison of these results clearly shows that the percentage of steel fiber contributes to the TBSCC bond strength, and conclusions are generated.
