Don > I'm not quite sure the term applies to building demolitions

It does, and particularly to 911. In fact, dust was found 10cm deep, 800m from the WTC which is an enormous quantity and cannot be explained by any other reason than actual pulverization of the concrete, and which was caused by means other than gravitational collapse. (Refs given in previous post)

Furthermore, there was a veritable wave of heat and dust which chased those fleeing as they ran from the disaster. This is typical of a pyroclastic flow.

The very small size of the dust particles is also typical of pyroclastic dust, whether from volcanoes or concrete destruction/dehydration by means of explosives, which is the only other way I understand the dust can be produced.

> I'd tend to question the so called pryoclastic effect as being overly significant, or the idea that there shouldn't have been that much dust.

That's your prerogative. In my opinion, the voluminous quantity of fine dust is one of the "smoking guns" which supports the use of explosives and is thus of considerable importance.

Don > RE: pyroclastic dust - I'm not quite sure the term applies to building demolitions

I think you are right. Perhaps a better description is "pyroclastic-like" or "quasi-pyroclastic".

I originally read on the internet that the dust, which was associated with the destruction of the WTC on 9-11, was called simply "pyroclastic" but now I see few sites carry that description. So, clearly, it is not scientifically accurate to describe the dust that way. But there is no doubt that enormous amounts of dust were produced, whatever the correct name for it is, if, indeed, there is one.
