The aim of the present research work is to investigate the possibility of adding a mixture of non-granulated blast furnace slag (NGBFS) and steel slag, two wastes resulting from metallurgical industry which underwent calcinations previously, in the raw meal for the production of Portland eco-cement clinker. For this purpose, the NGBFS and steel slag from ArcelorMitall Steel Galati were analyzed for chemical, mineralogical and heavy metals contents. Two samples of raw mixes were prepared, one with typically raw mat...

The production of the agglomerate is always related to the consumption of energy, occurrence of solid polluting substances and emissions, which are the main source of air pollution. The submitted work contains the analysis of knowledge obtained from the literature, but mainly analysis of the results gained from the laboratory sintering pan. This laboratory sintering pan sufficiently simulates conditions present on the sinter belt in relation to the production of CO, CO2, NOx, SOx and solid polluting substances in ...
