Concrete is pretty much always reinforced with steel rebar.

Yep! Concrete is great in compression shit in tension. Steel is great in tension and good in compression but expensive af (reletivly). So u can achieve material properties better than steel or concrete alone at a very efficient price by combining them.

One of god's gifts to man was giving us concrete and steel with the same thermal expansion properties.

I'm pretty sure I read that somewhere.
