Fiber reinforced concrete can be applied to precast concrete construction with excellent results and several key advantages:
- Better aesthetic quality of the product
- Higher mechanical strength in terms of toughness, flexural and shear stress
- Faster industrialized production process through the partial or total elimination of steel reinforcement cages
- Improved damage resistance during transportation and placing
- Reduced concrete thickness as no reinforcement cover depth is required
- Improved durability in aggressive environments
Steel Fiber Reinforced Concrete Precast Tunnel Segments
Tunnel segments are precast and packaged in a precasting facility before delivery and placement on site. Steel fiber reinforced concrete is cast or pumped directly inside the formworks.
With respect to design load conditions, it is possible to use 100% fiber reinforced concrete in precast tunnel segments.
