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.

How to Make Cement From Blast-Furnace Slag

Apr 23, 2017  The process of manufacture is very simple, and, in brief, is as follows:—. The dried granulated slag is mixed with a predetermined quantity of dry slaked lime and ground to an impalpable powder. It is then ready for use as cement. The slag sand, after being drained, still contains a large percentage of adhering water.
