Roman concrete, also known as opus caementicium, was developed around 300 BCE and is renowned for its durability and strength. The primary ingredients include volcanic ash, known as pozzolana, lime, and aggregates such as stones and fragments of brick. This mixture contributes to the unique properties of Roman concrete, including its ability to set underwater, which was especially beneficial for constructing harbors and other aquatic structures. The chemical reaction between the volcanic ash and lime results in the formation of a crystalline structure that gives the concrete its remarkable strength over time.
