     concrete is one of the most widely used construction materials which has both advantages and disadvantages. one of the disadvantages of concrete is its very low tensile strength leading to a sudden collapse and failure of concrete structures. the brittle concrete can be reinforced by steel reinforcement applied in the direction of tensile forces. however, in many cases, the direction of these forces is not exactly known. therefore, the need to high tensile strength and high-energy absorption concrete has been the reason for using fiber concretes in the past decade. fiber concretes are commonly produced by adding fibers to concrete mixture, as a reinforcement material, to enhance cohesion, tensile strength and crack propagation control in the elements of reinforced concrete; furthermore, it improves the energy absorption potential. in this paper, the mechanical properties of concrete with carbon fiber are investigated. fibers were added in different percent, 0%, 0.5%, 1%, and 1.5%, proportional to cement weight. all the samples were made from the same water-cement ratio. the produced samples were tested for compressive, flexural, tensile strength, impact test and water absorption at the age of 28 days. as it can be seen from the results, with the increase in the amount of fibers, the strength properties of concrete improves as well.
