GGBS | Aggregate Industries

GGBS. GGBS (Ground Granulated Blastfurnace slag) is perfect for use in concrete applications and large pours. Typically substitution rates are between 30-50%. GGBS reduces the risk of sulfate attack on the concrete. The reaction of the GGBS particles is also slower which makes it suitable for mass pours as the risk of thermal cracking is reduced.
