Abstract:
Seven case studies are presented in which low volume percentage (0.1 percent) synthetic fiber reinforced concrete (SFRC) was used for concrete slabs. Once low volume percentage SFRC cracks, the fibers generally do not restrain the cracks from widening. Fibers do help to control plastic shrinkage cracks and bleeding, and also provide some long-term performance advantage when concrete practices are marginal, but fibers are no substitute for good concrete. When using good proven concrete practices, including fast cut, closely spaced joints, reinforcement of any kind can be eliminated for many slabs-on-grade.
