Cement was made of hydrated lime (calcium oxide) mixed with sand and water. The Romans discovered that substituting or supplementing the sand with a pozzolanic additive, such as volcanic ash, would produce a very hard cement, known as hydraulic mortar or hydraulic cement. They used it widely in structures such as buildings, public baths and ...
Although different forms of cement already existed (Pozzolanic cement was used by the Romans as early as 100 B.C. and even earlier by the ancient Greek and Chinese civilizations) and were in common usage in Europe from the 1750s, the discovery made by Aspdin used commonly available, cheap materials, making concrete construction an economical ...
Above the ornate south doorway of Lichfield Cathedral stand seven figures carved in Roman cement. Roman cement is a substance developed by James Parker in the 1780s, being patented in 1796. [1] [2] The name is misleading, as it is nothing like any material used by the Romans, but was a "natural cement" made by burning septaria – nodules that ...
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.
The Romans also made bronze roof tiles. Lead was used for roof covering material and water supply and waste pipes. The Latin name for lead is plumbum, thus plumbing. Romans also made use of glass in construction with colored glass in mosaics and clear glass for windows. Glass came to be fairly commonly used in windows of public buildings. [2]
