Or is that a particular kind of metal used?
Rebar is just steel that has surface ridges on it so that the concrete can grip it better. There are lots of steel shapes used as concrete reinforcement, a wire mesh is often used in floors.
My brother had a friend many years ago that built a concrete boat and sailed around the word in it. The concrete was only 1/2 thick with many many layers of wire mesh reinforcement. The concrete surface was sealed with epoxy.
