Which is the better building material? Concrete or steel?

Concrete: Concrete is a material that is often locally sourced and thus typically requires minimal energy to transport to building sites. Rebar for concrete is often produced from recycled steel. At end of life, concrete can be crushed and recycled but the recycled material cannot be used for new building concrete. Steel:

Aggregate in Concrete

Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good quality, durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete, with mix adjustments made, as needed.
