This Specification covers the performance requirements for the use of fiber-reinforced concrete in slabs-on-ground and overlays, and includes provisions for the minimum equivalent flexural residual strength required for the fiber-reinforced concrete. It applies to the use of steel, synthetic, and glass macrofiber used to replace reinforcing steel bars and welded-wire reinforcement. This Specification is intended to supplement the requirements presented in ACI 301 and not intended to be a standalone specification. The use of microfibers for plastic shrinkage crack-width control is not covered by this Specification. Keywords: equivalent flexural residual strength; fiber(s); fiber-reinforced concrete; overlays; slabs-on-ground.
