This paper presents the comparison of the test results for material behavior for dry cast steel and synthetic fiber reinforced concrete. ASTM C1609 flexural beam test were carried out for two different fiber dosages of synthetic and steel fibers. Synthetic and steel fiber dosages were 2.4 kg/m3 and 13.1 kg/m3, respectively. From the results of tests, material properties were found including; compressive strength, first-peak load, peak load, and specimen toughness. ASTM beam load- deformation plots were obtained for each fiber beam to show the fiber behavior and strengthening after the initial crack.
