1.Feature
Length:8-16mm(this is the common size, any is available if required.)
Diameter:0.2mm+/-0.02mm
Tensile strength: above 2850Mpa
Shape:flat straight
Appearance:bright and clean

2.Advantage
Micro copper steel fiber is mainly used for the reactive powder concrete, also called UHPC(ultra high-performance concrete).
The micro copper coated steel fiber reinforced concrete has the 8 times compressive strength than the common concrete;
Fflexural strengths up to 50 Mpa
Modulus of elasticity 45 to 50 GPa
High bending tensile strength
low capillary porosity (high endurance)
High resistance to deicing salt
Greatly reduced permeability to moisture, chlorides and chemical attack
Increased resistance to abrasion, erosion and corrosion
Speedy construction

3.Applications
The micro copper steel fibers is widely used in the below areas.
Cast-in place structures
Tunnel
Subway
Mortars
Reinforcement of concrete
Other cementitious mixes

4.Packing
25kg/bag(kraft paper bag)
We also can pack it according to your requirement.
