25 Story Building Collapses in Brazil

This is interesting because the video clearly shows very large chunks of concrete being lifted from the rubble pile, which is to be expected in a gravity driven high-rise collapse. Of course there were no such large concrete pieces in the rubble pile of Towers 1 and 2, and Building 7; it was all reduced to powder.

WTC Concrete Floors

It's often said that "all" the WTC concrete floors turned to dust. In reality, it's a distribution of sizes. A more accurate way to put it is a very large fraction of the concrete was turned to dust.
