So if concrete structures from the Western Roman Empire can last for thousands of years, why does modern infrastructure look like this after only a couple of decades? Hey, I'm Grady and this is Practical Engineering. On today's episode, we're taking a look at the factors that effect design-life of concrete. (upbeat electronic music) (smooth upbeat music) If you haven't seen the previous videos in this series about concrete, here's a quick synopsis. We've talked about how concrete's made, why it often needs a reinforcement, and how that reinforcement can sometimes lead to deterioration.

We use steel as reinforcement because of its strength, its similar thermal…
