Why use Fly Ash and Slag in Concrete? Bay-Lynx

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 applications.
