Concrete has been an integral material in construction since the time of the Roman Empire. In fact, the earliest large-scale use of concrete was in the construction of the famous Roman landmarks such as the Colosseum and the concrete dome of the Pantheon; although small-scale uses have been seen as far back 6500 BC.
