Uhpc Copper Coated Micro Steel Fibers Series for Cement Reinforced
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.
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 | |||||
Advantages of Steel Fibers in Concrete
Reduced absorption of water, chemicals, etc.
Can be used on fast track schedule
Easier positioning of joints
Reduced site labor for managing steel reinforcement
Reduced project costs
Increased impact and abrasion resistance
Even distribution of fibers throughout the concrete
Tougher surface with fewer bleed holes
Savings will be greater for heavier crack control systems
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
