  • @pendejadafcc camera flash

  • what was the blue flash?

  • It's a good video no doubt, but i agree with @attaintruefreedom , it could have been hazardous if people seated too close got hurt with flying rubble!

  • @Nexxion its done hydraulically so its not going to fly out of control when it breaks! you can't compress a liquid so thats why it didn't much after it crushed it!

  • failed at 900,000 lb or 408 metric ton

  • note: crushes at 0:48

  • Once the load cell recognizes that the rate of the load increase decreases with time, that's when the operator stops it.

    Or when the concrete breaks :)

  • I spent many a night in Talbot Hall, where this video was taken.

    Kind of sad though that while I'm an UIUC engineering alum I never got to see the concrete crushing in person.

    ILL-INI!

  • Concrete needs to tested before any construction project to ensure it withstands the loads intended for it, I spent a whole summer testing cylinders like this one, although much smaller, for the Illinois DOT. Two samples of a mixture for every project are sent in and tested, if both pass you can assume the method works.

  • i want to see this done with aerogel
