Crimped Steel Fiber Is to Control Plastic Shrinkage & Drying Shrinkage

Round crimped steel fiber is fabricated by cold-drawn low carbon steel. Compared with rebar, round crimped steel fiber adds pull-out resistance. Round crimped steel fibers are deffer from other five types in shape but sharing the same functions. Round crimped steel fibers are designed to improve structural strength and durability, and also resistant to cracking and plastic shrinkage and drying shrinkage.

The characteristics of round crimped steel fiber changes with varying conditions, for example concrete, geometries, distribution, orientation and densities.

Crimped Steel Fiber Feature

1. Improve structural strength.
2. Reduce bleeding of water.
3. Resistance to cracking.
4. Improve freeze-thaw resistance.
5. Improve impact– and abrasion–resistance.
6. High tensile strength and good durability.
