The story of concrete is so ancient that we don't even know when and where it begins. It is a story of discovery, experimentation, and mystery. Emperors and kings became legends for erecting great concrete structures, some of which are still a mystery to engineers today. Many of history's most skilled architects found inspiration in slabs of the gray building material. Common bricklayers advanced the technology, and a con man played a crucial role in the development of concrete recipes.
Today, the world is literally filled with concrete, from roads and sidewalks to bridges and dams. The word itself has become a synonym for something that is real and tangible. Press your handprints into the sidewalk and sign your name to history. This is the story of concrete.
[...] Let's get this out of the way right here: cement and concrete are not the same thing. Cement, a mixture of powdered limestone and clay, is an ingredient in concrete along with water, sand, and gravel.
So ubiquitous and fundamental, that nobody thinks about it. Its inventor is unknown, but that person changed history.

No, it's not. Don't make the mistake of confusing the most durable works of ancient times with today's cheap stuff that is not intended to last a few decades, much less centuries.

Oh, yeah? Name one modern edifice that has lasted even one millennium, let alone two!
