Opus caementicium exposed within a characteristic Roman arch. In contrast to modern concrete structures, the concrete Employed in Roman structures was typically lined with brick or stone. The Romans utilised concrete extensively from 300 BC to Advert 476.[eighteen] In the Roman Empire, Roman concrete (or opus caementicium) was made from quicklime, pozzolana and an combination of pumice.
Via the late nineteenth and early 20th centuries, reinforced concrete had become a extensively adopted construction materials, revolutionizing architecture and engineering.
There are several cons involved with its use in building. Some of the important down sides of reinforced concrete contain:
Following is a bunch of article content that will be handy when trying to know more details on concrete and cement. Other items that might be of interest to you personally involve concrete Principles for example mix design, and cement data.
