EXPERIENCE WITH STEEL-FIBER-REINFORCED SHOTCRETE

Steel-fiber-reinforced shotcrete is a composite material consisting of concrete and long steel fibers which are applied together in the guniting process. Due to the interaction of the slightly deformable compressed concrete and the highly deformable steel fibers, a material with entirely new properties is obtained. Previous experience indicates that steel fiber reinforcement does not produce a crucial modification of the concrete's cracking behavior, but rather an increase of the deformation capacity under tensile and compressive loading and, especially, a substantial increase of the time and load-bearing capacity between initial cracking and severance due to fracture of the steel fibers. Steel-fiber-reinforced concrete has properties completely different from those of steel-reinforced concrete. The difference is not gradual, but rather of a fundamental nature.
