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 its ...
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.
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 ...
Ancient builders across the world created structures that are still standing today, thousands of years later — from Roman engineers who poured thick concrete sea barriers, to Maya masons who ...
Roman building ingenuity extended over bridges, aqueducts, and covered amphitheatres. Their sewerage and water-supply works were remarkable and some systems are still in operation today. The only aspect of Roman construction for which very little evidence survives is the form of timber roof structures, none of which seem to have survived intact.
Roman bridges were built with stone and had the arch as the basic structure. Most used concrete as well, which the Romans were the first to use for bridges. Roman arch bridges were usually semicircular, although a few were segmental (such as Alconétar Bridge). A segmental arch is an arch that is less than a semicircle. [87]
Whoa: Roman love letters and so many sandals The roller coaster, 70-mile-long turf and stone wall that Hadrian built coast to coast across northern England is a multi-site, must-visit Roman ...
Much of the practical skill and knowledge regarding the use of pozzolans was lost at the decline of the Roman empire. The rediscovery of Roman architectural practices, as described by Vitruvius in De architectura, also led to the reintroduction of lime-pozzolan binders. Particularly the strength, durability and hydraulic capability of hardening ...
