Now how they "differ" depends on what's in Steel besides Iron.

If the temperature changes, material expand with different rates. Concrete and steel expand with nearby the same rate, so that you can mix it.
Other materials would blow up the concrete if the temperature changes.
I was going to say the same thing, thank you.
One thing I wonder though, is since Iron and Steel are basically the same metal do they expand and contract at the same rate?
Or is the higher carbon in steel what causes the expansion/contraction to match concrete?
