Roman Inventions: Concrete

By Josh Yaklovich

Introducing Concrete

Rome was the first to invent what we call today concrete. Rome built a ton of structures made of concrete. Parts of the Colosseum and Pantheon were build with concrete. The Pantheon was one of the finest Roman structures and is still standing today. The name concrete comes from the Latin word "concretus" which means grow together. About 5 billion tons of concrete are used every year. In our world today concrete is a must or we probably cant imagine modern life without it.

How is concrete made?

Cement is the powder that reacts with water to form cement paste, a hard, solid material for the concrete. The addition of sand and rocks makes concrete. It has been know concrete is a porous material ( the properties depend on pore space).
