Railway Copper Coated Metal Fiber Reinforced Concrete 0.22mm
Micro steel fiber Introduction
Micro Steel Fibre is used in High Performance densified concrete system.
They are available in different diameter & length sizes,mostly are 0.2mm ,0.3mm in diameter and length in 6mm and 13mm.
Micro steel fibers are made of copper-coated steel wire which is the most important materials of UHPC. Because UHPC has the
features of extreme high strength. It is a good and a new kind of construction materials. Micro steel fiber is widely used in the
high speed railway slab, expressway, RPC coverplates and UHPC constructional components.
Dosage: 120kg/m3-200kg/m3
Mixing: When pouring sand and aggregates into the hopper, mix an appropriate amount of micro steel fibers
evenly, and then add cement ,mix for 2 minutes.
Application of Micro Steel Fiber
- Railway;
- Pipeline;
- RPC cover panel and precast unit
- High wear-resistant material
- Exterior wall painting
- Important engineering components
Specification of copper coated steel fiber for concrete:
| Micro Steel Fiber | Model | Diameter (mm) | Length (mm) | Aspect ratio (mm) | Tensile strength (MPa) |
| YS-0.22*13 | 0.22 | 13 | 59 | >2500 |
| YS-0.2*6 | 0.2 | 6 | 30 | >2500 |
| YS-0.3*18 | 0.3 | 18 | 60 | >2500 |
| YS-0.3*20 | 0.3 | 20 | 66 | >2500 |
In mechanical and performance terms, by adding steel fibers to the concrete mix can:
Increase and get a stable of tensile strength
Improve concrete bonding
Increase impact resistance
Increase fatigue effect
Increase crack resistance
Increase the concrete performance against thermal variations
