The Use of South African Fe-Mn, Si-Mn, Pt-Converter and Matte-Smelting Furnace Slags in Composite Portland Cement - First Results
In this paper the use of slags, from ferro- and silicomanganese alloy production as well as from the production of Pt-group element concentrates in blended cements, is discussed. The properties of the mixtures depend on the cement type, the mixtures, and the different manufacturers. Some cement performs better than others. The results are promising, but show variable behavior depending on slag and cement composition. Compressive strength tests as well as heat flow curves showing the hydration behaviour, indicate that 10-20 % addition of these slags to ordinary Portland cement is possible. These slags can be used as additions to cements to produce composite cements fulfilling the requirements up to 42.5N MPa class. By the addition of slag, the amount of calcium carbonate necessary for clinker production is reduced and, therefore, CO2 emissions are decreased. Also, large slag stock piles can be avoided.
