Micro steel fiber is a fiber material used to reinforce concrete and other composite materials. They are typically made of fine steel wires with high aspect ratios and small dimensions. Micro steel fibers have lengths ranging from 10 to 30 millimeters and diameters ranging from 0.2 to 0.5 millimeters.
Micro steel fibers provide several advantages when incorporated into concrete. Microsteel fibre significantly enhance the strength and durability of the concrete, improving its tensile and flexural properties. Additionally, micro steel fibers effectively control and slow down the formation and propagation of cracks, enhancing the material's toughness and crack resistance.
Micro steel fibers also contribute to increased impact resistance and fire performance. Microsteel fibre absorb and distribute impact energy, reducing the risk of material fracture and failure. In fire situations, micro steel fibers help prevent explosive spalling of the concrete surface, thereby maintaining the structural integrity and stability.
The use of micro steel fibers also improves the concrete's shrinkage resistance and reduces shrinkage-induced cracking. By providing restraint, the micro steelfibers alleviate internal stresses within the concrete, thereby extending the service life of the structure.
DAYE Copper/Brass Coated steel fiber is a special metal fiber with strong compression, tension and crack resistance.
