Abstract:
The influence of fiber type and fiber geometry on the fresh and hardened properties of ready-mix produced fiber reinforced concrete for exterior slab on grade applications was studied. Four commercially available steel fibers were investigated. This study indicated that the addition of steel fibers at 0.5 percent by volume did not significantly modify the characteristics of the hardened air-void system of the concrete. This study also demonstrated that the fiber geometry and the type of fiber used have a significant influence on the flexural toughness of the composite while other properties such as compressive and flexural strength remain relatively unaffected.
