Air Entraining

(OP)
A very simple question I simply can't find the answer to, what is the purpose of entraing air in concrete?

RE: Air Entraining

The primary purpose of entraining air is to improve resistance to the effects of freeze/thaw.

In my concrete book, it also says it improves workability, durability, and reduces segregation during placing.
