Endhooked Micro Copper Coated Steel Fiber For Reinforced Concrete Tensile Strength 2900Mpa
Micro steel fiber Introduction
Micro steel fiber ,is mainly used for high speed railway concrete cover
and important engineering construction, which has good prperties such as high strength 2500Mpa-2800Mpa,
abrasion resistance, crack resistance,bending resistance, anti-bending, impact resistance.
RPC (reactive powder concrete)has ultra-high strength, high toughness, high durability,is a high-tech concrete of
composite material.
Ultra-high performance concrete(UHPC) is an innovative concrete technology that is
rapidly gaining momentum throughout the world. With a compressive strength
of at least 150 MPa, the component materials self-consolidate to yield extremely
high durability and mechanical properties. UHPC is reinforced by micro steel fibers, which improve the material’s
tensile strength and energy dissipation capacity.

Even distribution of fibers throughout the concrete
Tougher surface with fewer bleed holes
Savings will be greater for heavier crack control systems
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. The steel fiber manufacturer can provide guidance on how
to mix and the amount needed to obtain the desired results. Be aware that if you add too much fiber,
it might show up at the surface when finishing the concrete so be cautious about the amounts being
mixed.
