Adding Fibers for Improving the Properties of Concrete and its Impact Resistance

This study is summarized in the search for the possibility of using fiberglass to improve the bending resistance of beams, and to obtain results that can be analyzed and some recommendations can be drawn, 18 concrete beams with a length of 70 cm and a cross-sectional area of 10x20 cm were cast and tested, five of them contain main reinforcement in the tension area and fiber-reinforced concrete that was placed in the casting mold at different depths from the lower surface level of the beams from the depth of the beam, and a beam without fibers was cast as a model for comparison, and the fifth reinforced with beams only in the shear areas was also used as a model for comparison, and 4 other beams not reinforced with main steel in the tension area and reinforced concrete for the depth of the beam and another containing normal concrete. Through this study, it became clear that the presence of fiber concrete in the compression zone for structural elements that are subject to bending clearly affects the structural behavior, as the amount of sagging increases, especially under the influence of weak loads, compared to the value of the total collapse load obtained from one of the beams that were tested.
