ABSTRACT
Fiber-reinforced concrete (FRC) is used mainly in relatively thick-section applications historically serviced by unreinforced or conventionally reinforced concrete. These include full-depth slabs on grade, overlays to existing slabs, and pneumatically applied shotcrete layers or linings used to stabilize, protect or rehabilitate exposed soil, rock, or deteriorated concrete surfaces, including surfaces exposed by tunneling. The minimum section thickness is usually at least 50 mm.
