abstract = "Synopsis: The effects of fresh state properties on the fiber dispersion characteristics of fiber-reinforced composites (FRCs) were studied by quantifying fiber segregation. Fresh state properties of concrete mixes were varied using different combinations of a plasticizing agent and viscosity modifier. A self-designed parallel-plate rheometer was used to obtain rheological parameters. Vibration was applied to the specimens and vibration times were varied to understand the effects of vibration on fiber segregation. An electrical characterization method, alternating current-impedance spectroscopy (AC-IS), was used to quantify fiber segregation in specimens. The relationship between fresh state properties and fiber segregation was evaluated.",
