Cement Historyof cement| Britannica
Cement-Cement- Historyof 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.

A Quick Method for Determining Cement Content of Fresh
Several attempts have been made to devise a method of determining thecement contentof freshconcrete. A few years ago a new concept of such a test was originated by R. A. Willis. To separate thecementfrom the aggregate, Willis employed a heavy liquid in which the aggregate would float but thecementbeing heavier would settle to the bottom.
