Abstract

The physical properties of concrete reinforced with polypropylene fibers are examined in this experimental investigation. Specifically, the properties of workability, compressive strength, tensile strength, and flexural strength (modulus of rupture) are investigated. Two separate concrete mixes are used; a high strength and a low strength mix. The effect of fiber length is examined by using three different fiber lengths. Several fiber contents are used in order to obtain an optimum fiber content for each of the properties and concrete mix. All of the test results are tabulated and presented in addition to a description of the fabricating and testing procedures that were used in the investigation. A statistical analysis of the test results for each of the properties is performed and the results are shown graphically.
