The purpose of this experimental research is to evaluate the mechanical properties of high performance concrete using amorphous steel fiber and organic fiber. For this purpose, the hybrid fiber reinforced concrete containing amorphous steel fiber(ASF) and polyamide(PA) fiber were made according to their total volume fraction of 0.5% for water-binder ratio of 33%, and then the characteristics such as the workability, compressive strength, and direct tension strength of those were evaluated. It was observed from the test results that the workability and compressive strength was decreased with increasing ASF and decreasing PA fiber. but the direct tension strength was on the whole increased with increasing ASF and decreasing PA fiber.
