Cement or concrete: think they're the same thing? Well, no—and the difference is more surprising than you might think. 🧱 In this video, we break down the real difference between cement and concrete: what cement actually is, how it's made from limestone and clay, what the famous Portland cement is, and how it transforms into concrete with water, sand, and gravel. You'll finally understand why almost everyone confuses these two words in everyday life. We also talk about the chemical hydration reaction, the Roman concrete that's still standing after two thousand years, modern concretes (self-healing, lightweight, reinforced), and even the environmental impact of cement.
