Overview
KingFiber ST75 is steel wire filaments with hooked ends. Steel fibers are designed for use with all types of concrete mixes to enhance mechanical properties and reduce plastic shrinkage cracking.
Applications
- KingFiber ST75 is ideally designed for use in the following applications:
- Shotcrete
- Tunnel segments
- Pre-cast concrete
- Industrial floors
- Composite decks
- Pavements
- Slabs on piles
- Foundation slabs
- Shear reinforcement in prestressed elements
Advantages
- Increase in load bearing capacity
- Increase in flexural bending strength
- Increase in fatigue and abrasion resistance
- Greater impact resistance and improved resistance to dynamic loads
- Reduction in shrinkage cracks due to full depth reinforcement distribution
- Economic advantage such as reduction in section thickness and construction time
- 1 - 2 hours fire rating
- STANDARDS KingFiber ST75 complies with ASTM A820, Type I and EN 14889-1
