Was the Concrete in the Twin Towers Actually Turned to Dust? If Not, What State Was It In?
The collapse of the World Trade Center towers on September 11, 2001, was a tragic event that has sparked much debate and speculation. One of the most common questions is whether the concrete in the towers was actually turned to dust.
The answer is no, the concrete in the Twin Towers was not turned to dust. However, it was severely damaged by the intense heat and impact of the terrorist attacks. The concrete was reduced to small pieces, but it was not completely pulverized.
The concrete in the Twin Towers was made of a type of lightweight concrete called perlite concrete. Perlite concrete is made with a mixture of Portland cement, perlite (a volcanic glass), and water. Perlite concrete is lightweight and has good insulating properties, making it an ideal material for use in high-rise buildings.
When the Twin Towers were attacked, the intense heat and impact of the explosions caused the perlite concrete to crack and break apart. The concrete was also weakened by the high temperatures, which caused it to lose its strength. As a result, the concrete was reduced to small pieces, but it was not completely turned to dust.
