Ladle metallurgy (LM) slag is generated during the refining process step in stainless steel making. In view of its very fine particle size, due to the transformation of β- to γ-C 2 S, and the Cr content, the slag is challenging in terms of handling and disposal and is used in only few applications. The current work explores the utilisation of the LM's fine …

One of these possibilities is the substitution of the cement by slag, which contributes to the reduction of cement consumption, decreasing CO 2 emissions, while solving a ...
In particular, efforts are made to valorize BOF slag as fine aggregates for the development of geopolymer based materials (highend application) by mixing it with other waste streams such as fly ...
The term "slag" is used for different materials which result from solidification of a melt.Sometimes it refers to pyroclastic rocks [], sometimes to ashes, e.g. from waste incineration, which have undergone sintering due to partial melting [], but mostly for pyrometallurgical residues which result from the reaction of slag-forming agents with …

A microelectrolytic filler (MEF) was prepared on the based on the concept of "treating waste with waste," using nickel slag as raw material through the carbon thermal reduction method. The degradation rate of methyl orange (MO) in water was used to evaluate the performance of the MEF. The effects of the preparation conditions and …
Calculations Relating to Concrete and Masonry. Sidney M. Levy, in Construction Calculations Manual, 2012 5.4.5 Ground Granulated Blast-Furnace Slag. Although portland blast-furnace slag cement, which is made by intergrinding the granulated slag with portland cement clinker (blended cement), has been used for more than 60 years, the …
Chemical resistance of commercial refractory raw materials against Cu slag is critical to consider them as candidates for the production of refractories used in Cu metallurgy. In this study, we show the comparative results for the corrosion resistance of four commercial refractory raw materials—magnesia chromite co-clinkers FMC 45 and …
The cement uses only 15-30% of OPC clinker, 30-40% of steel-slag and 40-50% of blastfurnace slag (BFS), allowing for great reductions in GHG emissions, consumption of natural resources and energy use by between 70% and 85%. The characteristics of steel-slag as a supplementary cementitious material are also discussed.
