Abstract:An accelerated method, perfected in 1968, has permitted to obtain in a few years a very large number of results which have been validly compared to earlier results obtained by long term methods. The performance of 130 cements consisting either of Portland cements of different types, or of cements with the addition of variable amounts of fly-ashes or slag, has been examined in three sulphate environments (MgSO4, CaS04, Na2S04) and in sea water. The results, regrouped in six classes of cements and presented in the form of comparative tables, permit to evaluate the performance of cements according to their type (type V, type II, Type I in accordance with the ASTM designation) and to know if they contain admixtures or not; in particular they permit to evaluate the role of C3A and the role of the slag. These results confirm that the choice of cements containing a high level of slag is justified for projects subjected to selenitic waters. The results also show that industrial cements with 15% addition of slag, fly-ash or pozzolan, used for many years in France, have an equally good performance.
