Since 1973 and at the request of the European Community which aims at removing trade barriers, the CEN (European Committee for Standardization) has undertaken to draft European standards (EN) for cements. Information is given on the progress of this work: 1. EN standards concerning test procedures and based on former International Organization for Standards (ISO) recommendations are for the major part ready for the final vote. 2. A draft nomenclature of cements, with particular emphasis being given to composite cements as a result of the energy crisis, has been drawn up while preliminary proposals for quality requirements are under consideration.
An analysis is also made of the contents of cement standards in European countries. Information is then given about the relative size of the current production of these four groups of cement—portland, portland composite (containing blast-furnace slag, natural pozzolana, fly ash, or even filler), blast-furnace, and pozzolanic—in Europe and in several other regions. Finally, possible developments in the types of cements to be produced between now and the end of the century are reviewed briefly.
