Crack Control Mechanism:

Cracks in concrete develop in the cementitious matrix between aggregates. Yian steel fibers, with ultra-high strength (>1000MPa after cold drawing) and dense distribution (tens of thousands per m²), effectively restrict crack initiation and propagation in floor slabs.

Steel fibers, with their high strength and modulus of elasticity, uniformly disperse throughout the concrete matrix. They Inhibit crack propagation by bridging cracks and transferring stress through interfacial bonding. Their geometric profiles enhance mechanical interlock, forming a three-dimensional reinforcement network that boosts flexural strength and toughness while inhibitting early shrinkage cracks.

Stainless steel fibers (tensile strength ≥1000 MPa, modulus ≈200 GPa) uniformly disperse in concrete to form a three-dimensional reinforcement network. Under cyclic loading, they Inhibit microcrack initiation and propagation by bridging cracks and transferring stress through interfacial bonding, delaying fatigue failure. Geometric features (end-hooks, corrugations) enhance mechanical interlock and bond strength, resisting debonding. This significantly extends fatigue life under repetitive loads, reduces fracture risk, and suits applications like bridges and airport runways subjected to alternating stresses.
