That's a good question, isn't it?

I know of many concrete cubes (roughly) serving as self support 
foundations for towers and satellite dishes that a "friend" installed 
decades ago without any re-rod cages, and none of them (to his 
knowledge) has split.

My friend became much more careful later on, but he always wondered 
about how critical it is in big blocks of concrete.

At any rate, I'm guessing that agonizing over tack welding the cage 
together (in a ham install) might be over thinking a bit.
