Shotcrete has normally been a mortar or concrete conveyed through a hose and pneumatically projected onto a surface at high velocity. A new wrinkle has been to include steel fibers in the mix. Fiber sizes used to date have ranged from one-half to 1 and one-half inches in length and from .010 to .016 inch in diameter. They have generally been applied by the dry shotcrete process in which the dry mixture is pumped through a hose and water added at the nozzle. Inclusion of steel fibers improves certain properties of either concrete or shotcrete, notably flexural strength, shear strength, toughness, impact resistance, the durability factor and the fatigue endurance limit. Toughness is increased 4 to 20 times over that of plain concrete if fiber content is in the range of .25 to 1.25 percent by volume. Dynamic strength or impact resistance is 5 to 10 times as great as that of plain concrete for various fiber loadings. Steel fibrous shotcrete placed by conventional machines has properties equal to or better than cast-in-place or precast steel fibrous concrete. It is being used in applications where its improved flexural strength results in savings on construction costs. Future potential applications include mine or tunnel lings, slope stabilization and thin-shell shapes such as boat hulls.
