Concrete | Can’t Sleep? Learn About the Foundation of Modern Cities

Concrete has shaped the modern world in ways most people rarely notice. This episode explores the history of concrete, how it is made, why it became one of the most widely used building materials on Earth, and how engineers continue to use it to create everything from roads and bridges to dams and skyscrapers. Along the way, you’ll hear about ancient Roman construction, cement production, reinforced concrete, and the science behind structures designed to last for generations. It’s steady and consistent, with no whispering and no sudden changes, just enough to give your mind something to follow as you wind down. Happy sleeping!
