ABSTRACT

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.
