Can Steel Fibers Bear Higher Strength?

How can steel fibers carry higher strength?

Steel fibers are a type of high-performance composite material that has been widely used thanks to their excellent properties. By using steel fibers, the stress concentration at the end of microcracks caused by loads on the matrix concrete can be greatly reduced, thus controlling the expansion of concrete cracks and improving the crack resistance of the entire composite material. Due to its strong crack resistance, high toughness, high impact and fatigue strength, as well as high tensile and bending strength, steel fibers are widely used in various fields, including roads, airports, bridges, waterworks, ports, railways, mines, tunnels, military and civil engineering.

Steel fiber salesmen know that the increasing number of cars not only brings traffic congestion problems but also brings greater load capacity to the roads, causing more severe road damage problems. Simple repairs are not very effective, and to make the road more capable of bearing weight, we need to develop more suitable and stronger products for road use. Steel fiber reinforced concrete is a product with better strength, which is made by mixing steel fibers and concrete in a certain proportion. Steel fibers, as a new and high-performance composite material, have been widely used and have achieved considerable success in coastal areas.

How can steel fibers respond to market development?

Steel fibers have high tensile and shear resistance, permeability resistance, low shrinkage and can effectively prevent shrinkage cracks. They can improve the impact resistance, fracture toughness, and processability of structural products. They distribute evenly and effectively in concrete without clumping or exposure. Under the same strength, steel fibers can save concrete consumption, replace or partially replace the reinforcement and shorten the construction period, especially suitable for large projects that require continuous rapid pouring of concrete.

Adding steel fibers to concrete can effectively prevent the expansion of microcracks inside the concrete and the formation of macroscopic cracks, significantly improving the tensile, flexural, impact, and fatigue performance of the concrete. Steel fibers with added waterproofing agents have moisture-proof, crack-resistant, wear-resistant and other advantages, making them ideal for waterproofing in basements and civil air defense projects. They can also be used in groundwater pump waterproofing. Steel fibers are a new type of multiphase composite material formed by adding transversely distributed short steel fibers to ordinary concrete, which significantly improves the tensile, flexural, impact, and fatigue performance of concrete and has good ductility.
