Experimental studies and optimization were carried out by determining the concrete mixture by creating Taguchi L16 (4^4) matrix. As a result of the analysis, steel fibers significantly increased the mechanical and impact strength of concrete due to their high strength and hooked end structures. On the other hand, the effects of polypropylene and basalt fibers was more limited. Basalt fibers, especially due to their microstructure and polypropylene fibers, had limited effectiveness due to their lower tensile strength. The amount of binder also plays an important role in the overall strength of concrete and it was found that the optimum binder content increased the strength of concrete. The results obtained from Taguchi analyses provide an important roadmap for the advancement of concrete technology. It is important to understand the effects of different types and amounts of fibers on the mechanical and impact properties of concrete.}, number={4}, publisher={TMMOB İnşaat Mühendisleri Odası}, organization={Süleyman Demirel Üniversitesi}
