Slag product appliions
· It generally requires an alkali activator such as hydrated lime or steel slag to be added to the product for this purpose. Ground Granulated Blast Furnace Slag (GGBS) Granulated blastfurnace slag is highly cementitious and after drying and grinding to a fine powder, it can be used as a replacement for conventional cement. The first commercially available Blastfurnace cement (a blend .
Iron and Steel Slags
Steel plants generate around 400500 kg of total slag per tonne of steel produced. Slags are generated at two different stages of steel production: Iron making and Steel making known as BF slag and Steel slag, respectively. These slags are in liquid state and are solidified in air after dumping in a pit or granulated by impinging water stream. Air cooled slags are larger in size (> 10mm) hence ...

Why use Fly Ash and Slag in Concrete?
It is is produced by the steel production industry. Slag happens when iron ore is melted. The molten iron sinks to the bottom, while the slag will float on the top of the iron. See the diagram below: Another difference between slag and fly ash is that while fly ash will rarely surpass 35% of the cement content, slag can substitute 50% of the cement content, or even higher for different ...
