Forta Ferro fibers offer an alternative solution for enhancing the tensile strength of concrete. In this study, 36 cylindrical and 36 cubic samples were tested using compressive strength, Barcelona, and double punch tests. The samples were aged for 28 days and contained 0, 1, 2, or 3 kg/m3 of Forta Ferro fibers. The results showed that adding 1 to 3 kg/m3 of Forta Ferro fibers to the concrete increased the 28-day tensile strength (BCN test) by 8.40% to 9.04% in cylindrical samples and 8.71% to 8.93% in cubic samples. Similarly, the 28-day tensile strength (DPT) increased by 6.81% to 9.42% in cylindrical specimens and 3.92% to 6.69% in cubic specimens when Forta Ferro fibers were added. The proposed Chen coefficient of 1.08 is suggested as the correction factor for the Forta Ferro fibers. Manuscript profile
