The floors were steel reinforced.
I can't imagine why a weak form of concrete would be used if the importance of strength was obviously shown by the fact that steel reinforcement was used.

<<< Well where is the specification for the floors? What kind of concrete was it? Was there any reinforcement? Were the floors used as diaphragms in the design? >>>

None of that is needed to determine that the concrete crumbled and that it was likely to crumble in a building collapse. You could answer your list of questions any number of ways and still come up with the answer; a massive building collapse is going to crush concrete.
