Someone had to come up with our language. So why not ancient people. Answer: The Romans
They stole Them from the Greeks
It came by the ancient romans
Concrete was basically used. The outside was faced with travertine and the upper levels were brick- faced concrete. Marble for the seating and decorative works. Iron for the cages and wood for the floor and elevators.
The best definition of concrete I heard was 'liquid stone'. And that's the way the Romans used it. In Reculver in Kent in England I was able to examine some Roman concrete close up in a fort and was astonished by its hardness considering it was 2,000 years old and close to the sea. My father was an architect and once told me the Romans used whites of eggs in their concrete mix to give it adhesion, strength and hardness.

The Romans invented concrete to build taller and more stable structures than ever built before. They invented the arch which can hold up a building with a single keystone.

The girls' name no doubt comes from the month which gets its name from the Romans. The derivation of the Latin Aprilis is uncertain- it may be derived from a word that meant to open up, as do the buds of spring.

It is unlikely that the Romans used knowledge of concrete gained from Mesopotamia. Concrete was made on a very small scale in Mesopotamia and the Romans devised their own concrete long before they got anywhere near Mesopotamia. A more likely source of inspiration would have been the Greeks who made mortars from a pumice called Santorin earth- named after the island where it was extracted. Pumice is a glassy volcanic rock. The Romans took cement making to a higher level. The kind of pumice they used was a finer grained one called pozzolana - named after Pozzuoli, a volcanic area by Naples. The Romans devised lime mortar-pozzolana pastes as binders for concrete (Vitruvius wrote of a 1:2 ratio for buildings and a 1:3 one for underwater concrete). Thus pozzolana was used as an additive to mortar, rather than using it alone as a mortar. When pozzolana is mixed with lime, it forms a light-weight, smooth, plaster-like concrete. Sand and stone rubble or rubble from previous buildings was used to add strength to it. The Romans invented a form of concrete which was much stronger than any previous one and which measures up to modern Portland concrete. The first known use of concrete by the Romans was the building of the piers of the port of Cosa (SW Tuscany) in 273 AD. Prior to this the Romans made their structures with rock blocks and bricks -which continued to be used.

Her backing of Marc Antony's rulership in the eastern part of the Roman empire pleased the eastern Romans but displeased the western Romans and Octavian Caesar.
