Ground Granulated Blast Furnace Slag

*Ground-granulated blast-furnace slag (GGBS)* is a byproduct from the blast-furnaces used to make iron. These blast furnaces operate at high temperatures, around 1500C, to melt iron from iron ore. GGBS Benefits: - *Sustainable*: Reuses blast furnace slag, reducing waste. - *Eco-friendly*: Lowers CO₂ emissions vs. regular cement. - *Durable*: Boosts concrete strength and lifespan. GGBS Drawbacks: - *Slower Setting*: May need additives to speed up. - *Variable Quality*: Depends on iron production processes.
