Concrete Does Not Dry Out – Minute Physics

If you’ve ever made pasta, you know what happens when you drop the noodles into a boiling pot: They absorb the water. Why? Pasta dries from an elastic dough as its water content evaporates. Compare this to concrete, “…a composite material composed of aggregate bonded together with a fluid cement which hardens over time.” It does not dry out. Minute Physics explains the chemistry and physics that make dams, bridges, towers, buildings, and other amazing structures so strong: Concrete Does Not Dry Out.

Watch these next: Shelter in 24hrs – Emergency Concrete-laced Canvas Tent, Chris Burden’s Beam Drop Inhotim, and Noodles & the principle of halving, a wonderful scene from The Ring of Truth.
