Granulated blastfurnace slag is a waste product of the steel industry that can be upcycled in cement to increase the strength and durability of concrete. A by-product of the steel-making industry, granulated blastfurnace slag (GBFS) is produced by the rapid cooling of iron ore slag. This creates a hydraulic material that is naturally ...
