A synthetic aggregate may also be the byproduct of manufacturing and a final burning process—blast furnace slag is an example of a synthetic aggregate. Briefly, blast furnace slag is formed when iron ore or iron pellets, coke, and a flux (such as limestone, CaCO 3, or dolomite, CaCO 3 ·MgCO 3) are melted together in a blast furnace. When the ...

GBFS. Granulated Blast Furnace Slag GBFS can be used like sand as an additional aggregate for building materials. Granulated Blast Furnace Slag is obtained by quickly chilling (quenching) the molten ash from the furnace with the help of water. Throughout this procedure, the slag becomes fragmented and changed into amorphous granules (glass).
