Micro Copper Coated Steel Fiber for Precast Concrete
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.

Advantages of Steel Fibers in Concrete
Several advantages can be obtained from this product, for example:
The increased load-bearing capacity of concrete
Reduction of concrete slab thickness
Load capacity is not diminished by concrete cracks
Increased durability
Low maintenance costs
Improved flexural properties
Reduced absorption of water, chemicals, etc.
Can be used on fast track schedule
Easier positioning of joints
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
