The Pantheon in Rome is an example of Roman concrete construction. Caesarea harbour: an example of underwater Roman concrete technology on a large scale. Roman concrete, also called opus caementicium, was used in construction in ancient Rome. Like its modern equivalent, Roman concrete was based on a hydraulic-setting cement added to an aggregate.

An example of a temple made of Roman concrete in the 1st century BC is the Temple of Vesta in Tivoli, Italy. The concrete was made of nothing more than rubble and mortar. It was cheap and very easy to produce and required relatively unskilled labour to use, enabling the Romans to build on an unprecedented scale.
For instance, the Ancient Roman civilization exploited curved structures for bridges, [5] aqueducts, [6] sewage ducts, and arch-dam. [7] The main materials of such constructions were Masonry and Roman concrete. [8] With the Industrial Revolution, the material chosen were more likely wrought, cast iron or, later, reinforced concrete. In this way ...
Aluminum-substituted tobermorite is understood to be a key ingredient responsible for the longevity of ancient undersea Roman concrete.The volcanic ash that Romans used for construction of sea walls contained phillipsite, and an interaction with sea water caused the crystalline structures in the concrete to expand and strengthen, making that material substantially more durable than modern ...
Concrete construction proved to be more flexible and less costly than building solid stone buildings. The materials were readily available and not difficult to transport. The wooden frames could be used more than once, allowing builders to work quickly and efficiently. Concrete is arguably the Roman contribution most relevant to modern ...
