Ultra High Tensil Strength Micro Copper Coated Wire for Concrete
Micro steel fiber Introduction
This micro steel fiber is made of copper wire.which is the most important materials of UHPC.
It has excellent tensile, bending and shearing strength, high tenacity,resistance against cracking,
impact and fatigue.
Micro steel fiber is widely used in the high speed railway slab, expressway, RPC coverplates and
UHPC constructional 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 |
How and When the Fiber is Added
Typically the fibers are added at the batch plant, just after all concrete aggregates are being mixed.
Some people would request to have the fiber added at the job site, but then the QA/QC should have more
control on how much fiber is added.
What is the use of steel fiber in concrete?
Steel Fibers are used as sprayed concrete (shotcreting),
slope stabilization, precast concrete production tunnel and mining shafts and underwater
concrete reinforcement. Steel Fibres are also popularly used in manufacturing precast walls,
overlays, manhole covers, piles & pillars.
