Steel Fiber Reinforced Foundation
Steel Fiber Reinforced Foundation
(OP)
A co-worker has asked me to help him investigate the properties of a steel fiber reinforced concrete foundation. We're looking for how it affects f'c, (phi)Vc, and how it compares to rebar reinforced foundations. All we were able to find online were research papers that had no difinitive explanations that apply to our questions, and ACI was no help due to the fact that this is more of a European practice. Any help leading us in the right direction would be great.
Thanks!
Thanks!

If there was any possibility of personnel working on their backs or having their hands near this stuff, I wouldnt recommend its use.

If your foundation is thick enough and if the flexural load can be safely carried by the plane concrete, you can use it. But you also have to take into consideration the application of the fiber. Further, any moisture barrier can be punctured by the steel fiber.
Note: Fiber reinforcement has also been successfully used in 'isotropic bridge decks' which utilizes them only for temperature and shrinkage control - where no longitudinal or transverse reinforcment is used.

Steel fibers in concrete come under ACI Committee 544. Most research and observation of actual practice shows that ductile steel fibers increase the capability to control cracks in concrete and enhance the compressive, tensile, and flexural strength parameters.
