GROUND GRANULATED BLAST-FURNACE SLAG MARKET OVERVIEW

The global Ground Granulated Blast-Furnace Slag (GGBFS) market size was USD 1.86 billion in 2025 and is projected to touch USD 2.74 billion by 2033, exhibiting a CAGR of 4.38% during the forecast period.

Ground Granulated Blast-Furnace Slag (GGBFS) is a finely ground, off-white powder produced by rapidly quenching molten slag from iron blast furnaces using water or steam. It largely contains calcium oxide, silica, alumina, and magnesia, and exhibits high cementitious capabilities, making it one of the suitable supplementary cementitious materials (SCM) in concrete. GGBFS, when mixed with water and calcium hydroxide, the reaction will react to form calcium silicate hydrates (C-S-H), and the cement will be firm and durable. It reduces the heat of hydration and applies to large structures such as dams and bridges. It enhances workability, reduces permeability and improves resistance to sulfate and chloride attack and thereby increasing the longevity of the structure.

GGBFS provides remarkable improvements in concrete performance, besides encouraging sustainable construction. Being the byproduct of the iron and steel industry, its use saves landfills and lowers CO₂ in comparison with the regular Portland cement. GGBFS provides long-term strength gains by mitigating issues such as alkali-silica reaction (ASR), and minimises reinforcement corrosion by limiting chloride ingress. It provides long-term strength increments and can therefore be used in demanding tasks such as marine construction, sewerage structures and high-quality concrete structures. GGBFS is a globally standardised product such as CEM III in EN 197, which has become more popular in contemporary construction due to its technical superiority, cost-effectiveness and beneficial environmental impact.
