Abstract

Using concrete reinforcement fibers improves the concrete desirable features including its strength, and sometimes provides the engineers with very light materials by reducing theconcrete’s weight. In the current study, type 2 Dashtestan cement, polypropylene, steel and glass fibers, and Superplasticizer were used in 9 mixture patterns to make the concrete. After they were built, concrete samples were kept in a regular water tank. Then, COMPRESSIVE AND FLEXURAL STRENGTH of samples were measured in 7, 28, and 90 days. Results indicated that polypropylene fiber reinforced concrete’s compressive strength curve, which was ascending at 1 percent range of fibers (the curve was upward), and descending at 2 to 3 percent fiber range (the curve was downward). In addition, Propylene fiber reinforced concrete’s flexural strength curve which was ascending at 1 and 2 percent range of fibers (the curve was upward). At 3 percent range of fiber, it was descending (the curve was downward) and the highest COMPRESSIVE AND FLEXURAL STRENGTH occurred at 1 and 2 percent range of polypropylene fiber respectively. Steel and glass fibers cause an increase in concrete samples COMPRESSIVE AND FLEXURAL STRENGTH. The compressive strength of steel and glass fibers reinforced concrete at 1 to 3 percent range of fiber with an upward curve. The flexural strength of steel fiber reinforced concrete at 1 to 2 percent range of fiber with an upward curve, and at 3 percent range it had a downward curve, and the curve of flexural strength of glass fiber reinforced concrete at 1 to 3 percent of fiber with an upward curve. The highest COMPRESSIVE AND FLEXURAL STRENGTH in steel fiber reinforced concrete occurred at 2 and 3 percent range of fiber respectively, and for glass fiber reinforced concrete, it was at 3 and 3 percent range of fiber respectively.
