Of course, just like firing many rounds rapidly out of a rifle will warp the thick steel barrel.
thats right— have you ever seen what cement does when heated— i tried it with a torch to see what would happen.. it pops like a firecracker and breaks off in chunks. (wear safty glasses)- when the beams weakened from the fire on the towers the top portion came down like a 100 ton wrecking ball, (thats why it was dust) — if explosives were used it would have been chucks flying off and not cement dust
