Cement History of cement Britannica

2020-12-12  Cement Cement History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe.

The History of Concrete and Cement ThoughtCo

2019-3-6  Cement is thought to be older than humanity itself, having formed naturally 12 million years ago, when burnt limestone reacted with oil shale. Concrete dates back to at least 6500 BCE when the Nabatea of what we know now as Syria and Jordan used a precursor of modern-day concrete to build structures that survive to this day.
