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.
#46 Roman Concrete Roman concrete, or opus caementicium, incorporated volcanic ash, making it incredibly durable. Structures like the Pantheon and aqueducts stand as testaments to its strength.
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 ...
It is a form of Roman concrete (opus caementicium), the main difference being the addition of small pieces of broken pot, including amphorae, tiles or brick, instead of other aggregates. [1] Its main advantage over opus caementicium was that it is waterproof, the reason for its widespread use in Roman baths , aqueducts, cisterns and any ...
The Romans made durable concrete strong enough for load-bearing walls. [26] Roman concrete contains a rubble of broken bricks and rocks set in mortar. The mortar included lime and pozzolana, a volcanic material that contributed significantly to its strength. [27] Roman concrete structures such as the Colosseum, completed in 80 AD, still stand. [28]
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.
Of the various ingredients used to produce a given quantity of concrete, the cement is the most energetically expensive. Even complex and efficient kilns require 3.3 to 3.6 gigajoules of energy to produce a ton of clinker and then grind it into cement. Many kilns can be fueled with difficult-to-dispose-of wastes, the most common being used tires.
