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 . Many buildings and structures still standing today, such as bridges, reservoirs and aqueducts, were built with this material, which attests to both ...
Ancient Roman concrete was a mixture of lime mortar, aggregate, pozzolana, water, and stones, and was stronger than previously used concretes. The ancient builders placed these ingredients in wooden frames where they hardened and bonded to a facing of stones or (more frequently) bricks.
Opus reticulatum (also known as reticulate work) is a facing used for concrete walls in Roman architecture from about the first century BCE to the early first century CE. [1]: 136–9 [notes 1] They were built using small pyramid shaped tuff, a volcanic stone embedded into a concrete core.
Archaeologists excavating the site of Pompeii have uncovered an ancient building site, revealing Roman construction techniques used by builders at the time, according to the Italian Ministry of ...
Starting around 200 BCE, the architects of the Roman Empire were building impressive concrete structures that have stood the test of time — from the soaring dome of the Pantheon to the sturdy ...
Calcium is a binding agent in Roman concrete, which makes it remarkably strong. Figuring out where it came from was the key to solving this architectural mystery.
With the introduction of Roman concrete, continuous outer walls were often constructed, with some blocks laid as headers in order to attach to the inner wall.Tile or marble can be found cemented to such walls, but this was less common for those structures that were particularly load-bearing, such as arches and pillars used for bridges and aqueducts.
Modern concrete crumbles in decades, but the concrete Colosseum still stands — a mystery that puzzled scientists. 2,000 years later, ancient Roman concrete still stands — and experts finally ...
