SpecFiber SPEC Steel fiber is a material with excellent performance and wid applications. Since steel fibers impede the expansion of cracks in the matrix concrete, the tensile strength, bending strength, shear strength, etc. of the concrete are significantly improved compared with those of ordinary concrete Its impact resistance, fatigue resistance, toughness and durability have also been greatly enhanced.
Function
It hinders the expansion of microcracks inside the concrete and blocks the occurrence and development of macroscopic cracks. Therefore, it has a remarkable improvement effect on the tensile strength of concrete, as well as the shear strength, bending strength, torsional strength, etc. which are mainly controlled by the principal tensile stress.
