60/25 Hooked End Loose Concrete Carbon Steel Fiber Resisting Crack In Shotcrete
Concrete Steel Fiber Introduction
Steel fibers mixed into the concrete can provide an alternative to the provision of conventional steel bars or welded fabric in some applications. However, it was during the 1970s that commercial use of this material began to gather momentum, particularly in Europe, Japan and the USA.
This concrete steel fiber is made of low carbon steel wire,high carbon steel wire,or stainless steel wire .
It has excellent tensile, bending and shearing strength, high tenacity,resistance against cracking,
impact and fatigue.
It is widely used for buildings, road surface, bridges, tunnels, airport road surface,water conservancy
projects, military engineering, hydro-project and all kinds of building products.

Advantage for Concrete Steel Fiber:
Steel fibers are typically added to concrete in low volume dosages, and be effective in reducing plastic shrinkage cracking.
Steel fibers typically do not significantly alter free shrinkage of concrete, however, at high enough dosages they can increase the resistance to cracking and decrease crack width.
