The Rebuilding Of The WTC

For the concrete that was used to build the World Trade Center, it would take 6 times as much as it was used to build the EIffel Tower. State-Of-The-Art concrete was used in 1 World Trade Center can withstand almost three times more pressure than the concrete used in most other NYC skyscrappers. So, the concrete that they used to build, well re-build the WTC, the concrete must have been thicker or something in that area, maybe tougher because it says that it was 6 times as much used to build the Eiffel Tower. Also the concrete can withstand almost three times more pressure than the concrete used in other NYC skyscrappers, meaning the new WTC is probably built in a better & stronger condition. Therefor, it wil be a better building, and last longer. They have prepared the building for something that may happen again in the future.
