No numbers, so you are still arm waving. I am familiar with the combustion energy of aluminum because of its use in large solid rocket boosters. The propellant is about 30% aluminum powder.
Pyroclastic clouds are hot ash made buoyant by the hot air entraining it. Volcanoes produce them, not explosives. I notice the continual oscillation between blaming "explosives" or "thermite." Explosives are not thermite, and thermite is not an explosive. Explosives generate large volumes of gas. Thermite generates a large amount of heat (from combustion of aluminum---which you should think abou,t if you want to pooh-pooh the energy available from aluminum combustion). More arm-waving. And I am beginning to suspect that these architects were in over their heads with this analysis.
What is there about "shattering, crumbling, and spalling" that is not "pulverization"? Reduction to dust is an outcome, along with all kinds of bits and pieces that cannot withstand the collision environment of a massive collapse. There would never be a stack of concrete pancakes. That would be the most amazing development of all. (A structural simulation of the WTC7 collapse showed an asymmetric process that involved the twisting and separation of the steel columns. Unless the floor slabs were intended for a hydroelectric dam, this would be like crushing a soup cracker.)
If clouds of dust proceeded from all three towers, the thing they had in common was a rapid chain-reaction compressive overload, and all the concrete breaking up upon impact with each other and with the ground.
