picket 9/11
The new World Trade Center is using a new kind of concrete called icrete, this will give the building more strength and more stability than the old building or any other building around. The icrete is able to be pressurized up to three times more than all of the skyscrapers in New York it has to be used with in 90 minutes of being mixed.The new walls are three feet thick and are re in forced with six times more steel than what was used for the Eiffel Tower.The middle of the building was called "basically a bunker" because of all of the saftey precausions taken, they hope that these precausions will help the minds of the up stered people be at rest as they come for there day to day travel to work.
