By reviewing the history and benefits of the use of glass fibers in concrete and by using a fixed mix design in this study, glass fiber lengths of 12 mm were used for the production of fiber concrete samples of 3 types of fiber-cement ratio () F C equal to 1.5%, 3%, and 4.5% and the effects of these parameters on the compressive and tensile strengths of concrete were assessed. The Portland cement utilized in this research was of type (I). The water used to produce the sample was local drinking

... ater. To select the reinforced concrete mix design, a compressive strength range of 36-54 MPa and density of about 2350 3 Kg m       were considered and the experimental projects were evaluated on this basis and 4 weighted mix designs were finally presented in this study. To compare the results, the fibers were distributed in the concrete as smoothly and uniformly as possible. The tested fibers were of glass type.
