Did the Roman invent concrete?

Question

i saw this on this web site on Roman, is this true or false

Answer 1

That can be complicated it is like asking if the French invented scrambled eggs. Several ancient cultures figured out how to make concrete but YES both Egypt and Roman Civilizations used concrete.

""""Concrete is a compound material made from sand, gravel and cement. The cement is a mixture of various minerals which when mixed with water, hydrate and rapidly become hard binding the sand and gravel into a solid mass. The oldest known surviving concrete is to be found in the former Yugoslavia and was thought to have been laid in 5,600 BC using red lime as the cement.

The first major concrete users were the Egyptians in around 2,500 BC and the Romans from 300 BC The Romans found that by mixing a pink sand-like material which they obtained from Pozzuoli with their normal lime-based concretes they obtained a far stronger material. The pink sand turned out to be fine volcanic ash and they had inadvertently produced the first 'pozzolanic' cement. Pozzolana is any siliceous or siliceous and aluminous material which possesses little or no cementitious value in itself but will, if finely divided and mixed with water, chemically react with calcium hydroxide to form compounds with cementitious properties.

The Romans made many developments in concrete technology including the use of lightweight aggregates as in the roof of the Pantheon, and embedded reinforcement in the form of bronze bars, although the difference in thermal expansion between the two materials produced problems of spalling. It is from the Roman words 'caementum' meaning a rough stone or chipping and 'concretus' meaning grown together or compounded, that we have obtained the names for these two now common materials.""

The Romans invented concrete, but not roads. The Achaemenid Persian empire had a system of hard roads long before the Romans. Take a picture of an arch; this was an architectural feature first used by the Romans. The Emperor Trajan built the world's first shopping mall 106 -112 AD, so you could take a photo of a shopping mall.

Answer 4

The words cement and concrete are both of Latin origin, reflecting the likelihood that the ancient Romans were the first to use the substances. Many examples of Roman concrete construction remain in the countries that encircle the Mediterranean, where Roman builders had access to numerous natural cement deposits. Natural cement consists mainly of lime, derived from limestone and often combined with volcanic ash. It formed the basis of most civil engineering until the eighteenth century, when the first synthetic cements were developed.

The earliest manmade cement, called hydraulic lime, was developed in 1756, when an English engineer named John Smeaton needed a strong material to rebuild the Eddystone lighthouse off the coast of Devon. Although the Romans had used hydraulic cement, the formula was lost from the collapse of their empire in the fifth century A.D. until Smeaton reinvented it.

Answer 5

Yes and no, roads were around long before roman influence however Rome was the first to bring about the use of highways, and pavement. This ment that the Roman roads were better suited to large military Traffic and wouldn't turn into muddy paths slowing movement. Cement was also around and rome did help to make it better but only some what, a better example of improvements made by rome would be a retirement system first given to its military after the reforms of its army. Also clear glass was a big advancement and the aqua ducts and sewage system

Answer 6

They invented something very close to the 'modern recipe', but cement is older than the Roman Empire. I think the Romans were the first to make a material you could pour as a 'bulk' building material, as opposed to cement to stick rocks together... but it's a bit of a fine line between one and the other, more an issue of quantity and the ratio of aggregate (rocks and the like to "bulk out" the mix) to cement.

Answer 7

egyptians did not use concrete, but limstone. the romans used a special type of concrete in which they mixed volcanic ash into the concrete mixture to form a super durable material.

Answer 8

It is true. During the Dark Ages, the people lost track of the recipe and had to build churches without concrete and mortar.

Answer 9

yes and there way was almost the same as ours is today, except without all the modern equipment and stufff...

Answer 10

Yes it was
