Many cements manufactured and marketed in different countries have generally similar properties, but national standards tend to characterize them using different tests and with different numerical values. A review has been made of the nature and the magnitude of these differences in order to establish those most favored in the world as a whole and also in a number of geographical regions. Greater harmonization of standards for many cements should be possible. Because of its growing acceptance in many countries, a move to the International Standards Organization (ISO) 679 test method for strength could provide a very useful starting point.
