Hollowcore floor slab with concrete form walls

[lizwid]

I am looking for some feedback on the pro's/con's of using hollowcore floor slabs in combination with poured concrete form walls for residential basement construction. Any comments?

There was an artical on concrete magazine a few month ago about pouring hi performance concrete with sphere on high rise building. I can only think of hallowcore as in forms of a sphere. More like plastic balls packed doun, and pour your 10k or more psi concrete down the basement.
