Concrete is the second most used material in the world, only exceeded by water. It is also one of our oldest construction materials starting thousands of years ago. It continues to evolve and allows us to make the tallest buildings, bridges, and roadways.

So how did our ancestors find out that if we heated rocks, we could make cement and then make concrete? How did we discover the multi-step process of making our modern concrete?

This presentation will take us through the journey of how cement and concrete developed. Along this journey, we will see how the discovery of fire, bricks, pottery, pyramids, and lighthouses played a major role in the development of concrete.
