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