Practical Engineering - Was Roman Concrete Better, 29102018

Comparing modern concrete to that of the western Roman empire In this video, 'Practical Engineering' discuss a few modern techniques that help improve design life of concrete, including roller compacted concrete (RCC) and water reducing admixtures (superplasticizers). There are a whole host of differences between modern concrete and that of the western Roman empire that I didn’t have time to go into, including freeze/thaw damage.

Tomorrow's Build - How Long Will Skyscrapers Last? 05072022

The supertall skyscraper is nearing its 100th birthday: with the Chrysler Building and Empire State Building over 300m tall. Skyscrapers, like every other building, have a shelf life, and as we build more and more of these massive structures it’s worth asking how long that shelf life actually is.
