An alternative to conventional steel reinforcement?

Steel-fiber-reinforced concrete for lining segments

To an increasing extent, specifiers envisage the use of steel fibers instead of conventional steel reinforcement to resist tensile forces in lining segments of tunnels or large sewers. Particularly on an international scale, this move is triggered by the necessity to build with steel-reinforced concrete under extreme conditions, for instance with respect to groundwater chloride content, and to enable service lives of more than 100 years. Whereas splitting tensile forces must be absorbed in the seal area during driving, the compressive strength of concrete would often be sufficient in installed...
