Working Principle
|
The working principle of steel fibers mainly depends on their bridging effect and stress transmission mechanism. When cracks appear in the concrete matrix, steel fibers will span over the cracks like a bridge. Due to the good bonding between steel fibers and concrete, it can prevent further expansion of the cracks. For example, when subjected to tensile stress, the stress at the tip of the crack will be concentrated, and steel fibers can disperse the concentrated stress to themselves and the surrounding concrete matrix, so that the crack will not easily penetrate the entire concrete component. This is the bridging effect of steel fibers. In addition, when concrete is subjected to external forces, stress can be transmitted from the matrix to the steel fibers through the interface between the steel fibers and the concrete. Because steel fibers have high strength and elastic modulus, they can bear some external forces, thereby reducing the stress borne by the concrete matrix. This stress transmission mechanism is similar to the role of fiber-reinforced matrix in composite materials. |

Product Structure
|
The product structure of steel fiber is mainly made of fine steel wire, with specific lengths, diameters, and aspect ratios. Steel fibers are usually made by cutting fine steel wires, shearing cold-rolled steel strips, milling steel ingots, or rapid condensation of molten steel. The commonly used long straight steel fiber with a circular cross-section has a length of 10-60 millimeters, a diameter of 0.2-0.6 millimeters, and an aspect ratio of 30-100. In addition, to increase the interfacial bonding between fibers and mortar or concrete, various shaped steel fibers can be selected, with cross-sections including rectangular, serrated, crescent shaped, and other shapes. |

Applications
|
Steel fibers are widely used in various fields such as construction, transportation, mining, protection, and industrial kilns. In the field of construction, steel fibers are added to concrete to improve its tensile strength, compressive strength, and toughness, reduce the occurrence of cracks, and extend its service life. Especially in housing engineering, steel fiber reinforced concrete is used to improve the seismic strength and ductility of nodes. In the field of transportation, steel fiber reinforced concrete is used for industrial flooring, roads, and parking lots, which can effectively resist heavy loads and impacts, reduce ground wear and damage, and improve performance. In addition, steel fiber reinforced concrete also plays an important role in bridge engineering, such as in the construction of ribbed arch bridges, which can not only reduce costs but also minimize seismic effects. In the mining industry, steel fibers can be used as reinforcement materials for shotcrete, improving the stability and safety of structures such as tunnels and mines, and reducing the risk of collapse. In terms of protective engineering, steel fiber reinforced materials are used in protective structures such as blast walls and protective screens in civil engineering to enhance their impact resistance. In addition, in the field of industrial kilns, steel fibers are used for lining bodies, containers, flow channels, and components, as well as for repairing kilns to enhance overall performance. For example, steel fiber castables may be used for key parts of electric furnace tops, heating furnace tops, and industrial boilers. |
