Who used concrete before the Romans perfected it?
The Egyptians because for there pyramids to make the big huge wall. NOT! I have no flipping clue who used concrete before the Romans!
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.
Did Romans give us cement and bricks?
No, the Romans did not invent bricks, but they did invent concrete.
What did the Romans develop to use for their construction?
The Romans were first to fully appreciate the advantages of the arch, the vault and the dome. The arch has a strong lad bearing capacity. The Etruscans invented the simple barrel arch and Pergamon invented the vault (adjacent arches which are assembled side by side) which has an even greater load bearing capacity and whose structure is also suited to support large roofs. The Romans invented segmental arch as they realised that an arch did not have to be a semicircle. The Roman used the arch to build gates, aqueducts, bridges which were much longer than before and could cross much wider rivers and valleys. The arches, especially the vault, became essential for the construction of large scale buildings. The Romans also developed a new and much stronger type of concrete which was as resistant as modern concrete and also set underwater (this enabled them to build much bigger docks for ports). However, it was not as fluid as modern concrete and had to be layered by hand. The arch, the vault and concrete were what made the construction of such a massive structure as the Colosseum possible. Concrete was also used to build domes. The Pantheon (a temple which has been turned into a church) in Rome is still the largest unreinforced concrete dome in the world. Often the Romans used a mixture of stone, brick and concrete (for the Colosseum stone and concrete were used). The Romans also used columns to build temples and porticoes. The Romans built scaffolding around what they were building. They adopted the cranes of the Greeks and massively improved on them. The simplest one was the trispastos, which had of a single-beam, a winch, a rope, and a block with three pulleys. It had had a mechanical advantage of 3:1, and single man operating the winch could raise 150 kg. The pentaspastos had five pulleys and the polyspastos had a set of three by five pulleys with two, three or four masts. The latter was worked by four men at both sides of the winch and could lift 3,000 kg. When the winch was replaced by a treadwheel, the load could be doubled to 6,000 kg with only half the crew, because the treadwheel had a larger diameter and thus a much bigger mechanical advantage.
What is before Romans in the bible?
No Romans existed way before Christianity
What did the Romans invent and why?
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.
Who used concrete before the Romans perfected it?
The Egyptians because for there pyramids to make the big huge wall. NOT! I have no flipping clue who used concrete before the Romans!

When did Romans invented the road?
The Romans invented concrete, not roads. Roads were around before the Rome existed.

What will happens if a mason does not mix the concrete thoroughly before he casts it?
The building would break down due to the concrete's weakness as some places are more concentrated than other
What is a pre cast concrete?
Precast concrete is a construction element made of that material and finished before its installation in the building frame. The mix of concrete must be cast or scaffolded until it gets enough strengh to handle and support own weight.
Who were the rulers of Italy before the Romans?
The Ethruscans ruled Italy before the Romans.
