Title: PROPERTIES OF POLYMERIC FIBER-REINFORCED CONCRETE
Accession Number: 00727332

Record URL: Availability: Find a library where document is available Abstract: The mechanical properties of lightweight and normal concrete containing nylon polymeric fibers are presented. Fiber reinforced concrete made with nylon fibers was evaluated. The 19-mm-long fibers were in single filament form. The control concrete was designed for a compressive strength of 20 MPa. The primary independent variable was fiber volume fraction. The response variables were air content, unit weight of fresh concrete, compressive strength, modulus of rupture (flexural strength) and toughness, splitting tensile strength, and impact strength. The addition of fibers decreased the slump values. The decrease was negligible at fiber contents of 0.45 and 0.6 kg/cu m. The fibers distributed well in the matrix. Fibers could be directly added in the mixer. The effect fibers had on unit weight of concrete is negligible. Addition of fibers up to 2.4 kg/cu m did not change the compressive, flexural, and splitting tensile strengths appreciably. Impact strength and flexural toughness increased consistently with the increase of fiber volume fraction.
