Difference between Fiber reinforced concrete and steel reinforced concrete?

Steel reinforced concrete is concrete that is reinforced by either metal reinforcement bar (rebar), wire mesh or some other kind of metal.

Fiber reinforced concrete is usually reinforced with some type of steel, but it is also reinforced by short linear fibers. These fibers can be made of several materials. The other answers cover this pretty well.

When breaking concrete cylinders without fiber reinforcement, you will observe that the concrete breaks off in chunks.

This is what would happen in the field too. Concrete that is reinforced with fiber doesn’t break this way. Instead the fibers lock together in the concrete to form an interlocking concrete.

These are the major differences between fiber reinforced concrete and steel reinforced concrete.
