Ground Granulated Blast Furnace Slag (GGBS) is a finely ground byproduct of the iron-making industry, formed by quenching molten iron slag with water or steam. Known for its pozzolanic and latent hydraulic properties, GGBS is widely used as a supplementary cementitious material in concrete production. By replacing a portion of the Portland cement content, typically up to 50%, GGBS enhances concrete performance by reducing heat of hydration, improving workability, reducing permeability, and enhancing sulfate resistance and alkali-silica reaction mitigation. Its application extends to various construction projects, including mass concrete structures like dams and foundations, where its low heat of hydration and reduced thermal cracking potential are advantageous. Moreover, GGBS contributes to environmental sustainability by conserving resources and repurposing industrial byproducts, aligning with the principles of circular economy in the construction industry.
Ground Granulated Blast Furnace Slag (GGBS) is a finely ground powder obtained from the rapid quenching of molten iron slag produced during the steel-making process. Composed mainly of silica, alumina, and calcium oxide, GGBS enhances concrete performance when used as a partial replacement for Portland cement.
