How did ancient rome build their houses?

Answer 1

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.

Answer 2

they would make it with different things such as concrete stone wood and sometimes even marble
