Mar 01, 2000 1. Introduction. Since the first discovery of cementitious properties of blast furnace slag BFS by Emil Langen in 1862 and particularly after the oil crisis in 1970s, manufacture of blast furnace slag cement BFC has substantially increased due to greater emphasis on energy conservation, utilization of waste materials and certain technical advantages over ordinary Portland cement OPC ...
Figure 5.3 shows an example of the changes in CO 2 emissions from the process of producing blended cement. This example the shows effect of the substitution of clinker by granulated slag for a CEM IIB-S 32, 5 with 35 granulated slag. It can be seen that, on the one hand, there are savings in CO 2 emissions from fuel consumption, from electricity consumption and from limestone decarbonation.
