Studies of Using Slags from Ore Based Steelmaking to Produce Sulphoaluminate Belite Cement with Reduced CO2 Emission
The aim of the present studies is to examine the potential for using basic oxygen furnace,ladle and blast furnace slags from Swedish works of ore based steelmaking in production of clinkers for sulphoaluminate belite cement.The slags and chemicals were mixed to form briquettes for burning at 1300℃.Samples of the clinker briquettes obtained were characterized by different methods.The sulphoaluminate and other phases in the clinker samples were detected by XRD.These and other results showed that the slags can be used in the cement,stabilizing belite phase in the clinkers and enhancing heat fluxes or the degrees of hydration measured in the early,24-hour period for the clinkers,thus to allow for more sustainable steel and cement production.
