RPC Micro Copper Coated Steel Fiber for Concstruction and Engineering Project
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.

Benefits by adding steel fibers to the concrete mix:
- 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
- Reduced site labor for managing steel reinforcement
- Reduced project costs
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.
