“…Also, studies on amorphous steel fiber reinforced concrete have been conducting to further improve the flexural toughness and strength than the conventional steel fiber reinforced concrete (Choi et al 2015;Hameed et al 2010; Kim et al 2016). Recently, many studies are focusing on hybrid fibers such as combination of steel fiber and organic fiber that materials properties differ from each other and combination of macro fiber with large dimension and diameter and micro fiber with small dimension and diameter (Lawer et al 2000;Qian and Stroevenb 2000;Song 2011;Yang 2010;Yao et al 2003). Studies on characteristics of hybrid fiber reinforced concrete using amorphous steel fiber and polyamide fiber, however, yet remain to be done.…”

Many studies have been performed on hybrid fiber reinforced concrete for years, which is to improve some of the weak material properties of concrete. Studies on characteristics of hybrid fiber reinforced concrete using amorphous steel fiber and polyamide fiber, however, yet remain to be done. The purpose of this experimental research is to evaluate the workability and mechanical properties of hybrid fiber reinforced concrete using amorphous steel fiber and polyamide fiber. For this purpose, the hybrid fiber reinforced concrete containing amorphous steel fiber(ASF) and polyamide fiber(PAF) were made according to their total volume fraction of 0.5 % for water-binder ratio of 33 %, and then the mechanical properties such as the compressive strength, direct tensile strength, flexural strength, and flexural toughness of those were estimated. It was observed from the test results that the compressive strength was slightly decreased with increasing ASF and decreasing PAF and the effect of fiber combination on the flexural strength was not much but the flexural toughness was relatively largely increased with decreasing ASF and increasing PAF.
