Impact Resistance Concrete Steel Fiber Cracking Resistance High Performance
Impact Resistance & Cracking Resistance Micro Steel Fiber High Performance 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.

Benefits by adding steel fibers to the concrete mix:
- 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
- Increased impact and abrasion resistance
- Even distribution of fibers throughout the concrete
- Tougher surface with fewer bleed holes
