This study examines the effect of fiber properties, single fiber type and hybrid fibers on the
fresh-state and hardened-state properties of self-consolidating fiber-reinforced concrete
(SCFRC). As part of the study, 16 mixtures are examined with variables including the effect of
fiber type, length, aspect ratio, and hybrid use of fibers (short and long fibers). Properties in the
fresh state are studied using standard SCC tests including: slump flow, V-funnel and visual
stability index (VSI) tests. Mechanical properties are studied by testing prisms under four-point
flexural loading in accordance with the ASTM C1609 standard. The results demonstrate that
self-consolidating FRC mixtures are possible at moderate fiber contents, however, once the
limiting fiber contents are exceeded workability and mix uniformity are lost. The results also
show the effects of fiber content, fiber type, fiber properties and hybrid fibers on the flexural
toughness of SCFRC.
