The first surviving reference to concrete is in the architecture books by Vitruvius written around AD 25-25. It is likely that concrete was perfected in the 1st century BC. In the mid-part of that century, the Roman had worked out how to make underwater concrete. A breakwater in the Bay of Pozzuoli Bay, at the northern tip of the Gulf of Naples is dated to 37 BC. The Romans used a mix of lime and pozzolana (a volcanic rock) as a mortar to which they added aggregate. Pozzolana is named after Pozzuoli, a suburb of Naples which is in a volcanic area and where this rock is abundant. Vitruvius wrote that the best maritime concrete was made with volcanic rock from the area of the Gulf of Naples.
