The present work describes the results of an experimental investigation on the performances of concrete specimens reinforced with steel fibers using the double punch test (DPT). The DPT is an indirect tensile test based on the configuration of double-punch test, named, Barcelona test that was developed for the systematic control of fiber reinforced concrete. DPT can be carried out by testing 150 × 150 mm concrete cylinders subjected to double punching test. Previous experimental results have showed that DPT gives significantly lower variability compared to other test methods. In the test performed, indirect tensile strength and fracture toughness result obtained by DPT were compared using molded cylinder and core concrete specimens.
