CementHistory of cement Britannica

CementCementHistory 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 2 000 years ago and of subsequent construction work in western Europe. Volcanic ash mined near
