What was the mountain that roman conceret came from?
Roman concrete did not come from any mountains. The Romans used pozzolana to make concrete. They mixed it with lime. Pozzolana was a volcanic rock which came from Pozzuoli, a suburb of Naples.
When was the pazzolana invented?
There isn't an exact date on when pozzolana was invented. ÊIt was used in Eastern Mediterranean about 500 toÊ400 BC. ÊIt was made by the Greeks but the Romans developed it fully.
Where did Romans get cement?
The Roman buiders used volcanic tuff ash found near Pozzuli village near Mount Vesuvius in Italy.Volcanic tuff or ash mostly sillicious in nature.Thus the named as pozzolana.
Did The Romans used the knowledge of concrete that they gained from the Mesopotamians in order to help build their aqueducts and other structures?
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.
What was the name of the volcanic stone native to Italy used by the Romans before concrete was used on the building scene?
The first stone whuch they used was tuff. Then they startted using peperino. Pozzolana was used to make concrete
When did the Roman's perfect their concrete?
The first surviving reference to concrete is in the architecture books by Vitruvius written around AD 25-25. It is likely that concrete was perfected in the 1st century BC. In the mid-part of that century, the Roman had worked out how to make underwater concrete. A breakwater in the Bay of Pozzuoli Bay, at the northern tip of the Gulf of Naples is dated to 37 BC. The Romans used a mix of lime and pozzolana (a volcanic rock) as a mortar to which they added aggregate. Pozzolana is named after Pozzuoli, a suburb of Naples which is in a volcanic area and where this rock is abundant. Vitruvius wrote that the best maritime concrete was made with volcanic rock from the area of the Gulf of Naples.
How would you describe the Roman approach to science and technology?
The Romans did not have much of an approach to science. In fact, were not interested in science and they hardly gave a contribution to science. Pretty much all of the science legacy from antiquity is from the Greeks. With regard to technology, the Romans were good engineers. This came from their being very practical and their penchant for finding solutions for practical problems.
How long have people been finding fossils?
since the early Greeks and Romans
What might explain why Greeks were more interested in idealization than the Romans?
The greeks believed in gods. Romans belived jesus was the son of one true god.
Is it true that Romans wanted their art to be useful while Greeks were more interested in beauty alone?
It is true that the Romans had a more utilitarian approach than the Greeks.
Were the Greeks or the Romans more practical?
The Romans were more practical, although this does not amount to saying the the Greeks were not; they certainly were. The Romans were less interested in science and theoretical thinking than the Greeks. They were great engineers and focused on the infrastructural development of their empire.
How did the romans make cement?
The Romans made cement by mixing lime (calcium oxide) with volcanic ash, known as pozzolana, and water. This combination created a hydraulic cement that could set and harden even underwater. The addition of aggregates like sand and crushed stone enhanced its durability and strength. This innovative material was crucial for their construction of structures like aqueducts, baths, and the Pantheon.
