Okay, just a couple points I can respond to.
First, concrete turning to dust doesn't somehow prevent steel doing something else. They're different materials that respond differently, specifically chemically differently in the presence of thermite.
Nothing reasonably proposed besides incendiary compounds like thermite provides the necessary heat to utterly destroy the tensile strength of the massive steel in the towers, and because it specifically reacts chemically with iron, concrete is not so affected. Ordinary explosives, or even exotic explosives, turned the concrete into dust, while the steel melted and burned.
Experts, while not gods, are experts because they have specific knowledge and experience, and that's what it took to drop the towers into their footprints. 9/11 was done by experts in demolitions.
I listen to experts, at least them as are trustworthy (which excludes them as appear on TV almost completely), because I am expert in almost nothing. I don't just accept what they say, but hear it and do my best to judge it rationally.
That's all ordinary folks can do.
You ask where are the pools of molten steel, but the images in the links and the commentaries discuss this. Generally, after they cooled sufficiently they were sent off to be recycled in Thailand or somewhere. At the time I was aware of the pools (they were in the news for weeks, and I knew burning desks and passports (a joke) didn't provide sufficient heat to create them.
I want to state here that I misinterpreted your responses to me as coming from someone denying 9/11 was a false flag terrorist attack and supporting the official conspiracy theory, which I felt obligated to refute.
I am comfortable disagreeing with you regarding technical details regarding the molten steel and concrete dust. I know there are myriad details reasonable people will never completely agree on regarding just what to have for lunch. How much disagreement has been made unavoidable by the deliberate coverup and destruction of the 9/11 crime scene?
As long as we are both aware 9/11 was a false flag terrorist attack that elements of the USG (and their allies and minions) committed against the American people to precipitate the police state here and permanent state of war in the ME, I am not interested in opposing you regarding technical details of the behaviour of the materials in the towers.
I may not agree on those details, but those aren't the important details that have compromised the security and felicity of America, and the people of the world through the actions of deranged terrorists.
If we agree on that, we agree on the important issue regarding 9/11.
