Abstract

The fiber in the concrete serves to prevent cracks in the beam so that the flexural strength of the beam increases. The purpose of this study was to analyze the ability of galvanized wire fibers to increase the flexural strength of beams. Galvanized wire with a diameter of 0.2 mm cut to a length of 12 mm, with a fiber content of galvanized wire varying at 4%; 6%; 8%; and 10% by weight of cement. There are a total of 25 test objects in the form of blocks. This test uses a Hydraulic Concrete Beam according to ASTM C78 (Flexural Beam Testing). The results of this study indicated that the fiber content of 0%, 4%, 6%, 8%, and 10% were 6.17 Mpa, 8.08 Mpa, 9.41 Mpa, 11.75 Mpa, and 10, 17 respectively. Mpa. So it was found that the fiber content with the highest average flexural strength value was 11.75 MPa while the lowest average flexural strength value was 8.08 MPaThe results of this study indicated that the fiber content of 0%, 4%, 6%, 8%, and 10% were 6.17 Mpa, 8.08 Mpa, 9.41 Mpa, 11.75 Mpa, and 10, 17 respectively. Mpa. So it was found that the fiber content with the highest average flexural strength value was 11.75 MPa while the lowest average flexural strength
value was 8.08 Mpa
