Can air fires make solid concrete explode into fine powder after a 1 hour delay period?

Question

FACT 1: Concrete has a tensile yield strength over 4000 psi (around 27 MPa to 42 MPa) and is much stronger in compression.

FACT 2: Air fires burn at around 250 C, much much lower than the melting point of concrete (between 1800C - 2500 C)

FACT 3: Melting point of steel is about 1532C, so

How could so much concrete powder be created as the WTC Twin Towers were falling, if they stood strong and stable for over 56 minutes to about 80 minutes after jet plane impacts? Also, how did Building 7 just collapse into itself 7 hours after the twin towers collapsed, when it was not hit by any plane?

ANSWER: Pre-planted controlled demolition explosives being triggered sequentially, so that all the support steel could be sliced quickly with cutter charges (like thermite) and any concrete columns could be blasted away by explosives, to allow a free-fall (zero resistance) vertical collapse.

Answer 1

honestly im starting to believe that most people who haven't figured out it was an inside job by now are sheep that never will, are too brainwashed and dont want to accept the real world cause its scary and will shatter their old conception. If someone isnt curious enough then forget them, move on, they will learn soon enough when the police state is on us. ha, uff, baaaaa

Answer 2

So how did they make absolutely sure that the planes hit the buildings on the exact floor where the charges were placed? If you look at the video of the collapse, you can see that the collapse doesn't start from the bottom, it starts from the height where the planes hit. Also, there is no explosion when the buildings collapse, as there is when buildings are demolished with explosives - it appears that the structure fails and that the rest of the building simply cannot sustain the impact of collapsing upper floors, so the whole lot goes down. Also, how could massive amounts of explosive be put in place without anyone knowing or questioning it? If you look at how tall buildings are demolished, they have to jacket the vertical supports with massive 'belts' of explosives. Hardly something you can sneak in when no-one is looking. It would be blindingly obvious to everyone who worked there.

Answer 3

very properly, #a million your info are incorrect. the place did you get them? Hydrocarbon fuels can burn at temperatures as much as 1600C. Even paper fires are approximately 800C. If the fire seems crimson, then its a minimum of 800C. If is yellow its in all probability 1200C and if its white is 1600C or extra desirable. shade of fire may well be a reliable indicator of temperature. Heres how metallic supplies way under average fire temperatures. we could basically say that the fire from that jet gas replaced into warm, yet no longer quite warm for a hydrocarbon gas, say 800-1000C. certainly no longer sufficient to soften metallic (some steels soften as low as 1148C, yet we dont could desire to pass there to describe this). ok so now we evaluate what takes place to metallic at 800-1000C. The shape of metallic is perplexing and robust because of the fact it has many deformations, form of like tiny cracks and bends in the metallic shape. those are put in place intentionally throughout warmth remedies and/or chilly working. whilst metals are heated up, the form has extra capacity to pass around and it resettles right into a aligned crystal shape. The shape isn't as inflexible. in certainty maximum steels under a million.5% carbon will incredibly replace shape decrease back to gamma iron (austenite). Austenite at this teperature is comfortable and bends certainly. that's why blacksmiths warmth metallic swords in the previous they smash them. they are comfortable and extra certainly replace shape. Now in case you knew something approximately textile sciences in the previous you asked the question you have conventional that jet gas could certainly soften the metallic. And pondering the a lot of concrete it replaced into preserving, the on the spot as quickly as bar began to bend because of the fact of misplaced power, all of them could have because of the fact further and extra weight could have been utilized to each and each.

Sorry, The X-Files went off the air, but some outlets still carry
them in reruns, it was a great show.

Answer 5

How funny is it that the military intelligence created the internet to kill people more efficiently and it is now exposing all the immoral killing they have engaged in?

How you gonna stop it spooks? Your voices are getting weaker and more petty.

Answer 6

It was an inside job and all about numbers, dates, and the occult!...
