Ground granulated blast furnace slag prices in Germany, the highest-cost reporting region, rose 6.5% in H1 2026, climbing from USD 0.124/KG in Q1 to USD 0.132/KG by Q2 as recovering construction and cement sector demand and tighter slag availability from lower blast furnace operating rates supported the market. Globally, the average rose from USD 0.0824/KG in Q1 to USD 0.0874/KG in Q2, a 6.1% gain. For H2 2026, a global average of USD 0.088-0.098/KG is expected, with continued firming on infrastructure investment acceleration and growing sustainable construction and low-carbon concrete sector demand.
Ground granulated blast furnace slag, widely referred to as GGBFS or GGBS, is a latent hydraulic binder produced as a by-product of pig iron manufacture in blast furnaces, where molten slag is rapidly quenched with water or steam to produce glassy granules that are subsequently dried and ground to a fine powder. The largest pull comes from supplementary cementitious material applications in concrete production, where GGBFS partially replaces ordinary Portland cement to reduce heat of hydration, improve long-term strength, enhance resistance to sulfate and chloride attack, and significantly reduce the embodied carbon footprint of the concrete mix. Additional demand comes from slag cement production, geopolymer binder formulations, ready-mix and precast concrete manufacturing, infrastructure and marine construction applications, and ground improvement and soil stabilisation treatments. Blast furnace operating rates at integrated steel mills, electricity and grinding costs, cement and construction sector demand, and environmental regulation supporting low-carbon concrete all feed into the price.
The balance of supply and demand for ground granulated blast furnace slag through H2 2026 leans moderately firm. Slag availability tightened with moderating blast furnace operating rates at integrated steel mills in Europe and North America. Cement and ready-mix concrete sector demand is growing with recovering construction and infrastructure investment activity across key markets.
The main upside risk is a sharp reduction in blast furnace operating rates alongside accelerating green concrete adoption mandates that tighten slag supply relative to demand. The main downside risk is a steel production recovery that significantly increases slag by-product availability and limits the price recovery.

Supplementary cementitious material applications in concrete production take the largest share, replacing ordinary Portland cement to reduce heat of hydration, improve long-term strength, and lower embodied carbon. Slag cement, geopolymer binders, marine and infrastructure concrete, and ground improvement treatments also consume significant volumes.
The Q2 2026 average was USD 0.107/KG in the United States, USD 0.066/KG in China, USD 0.132/KG in Germany, and USD 0.101/KG in India. Germany remains the highest-priced market.
The global average rose from USD 0.0824/KG in Q1 to about USD 0.0874/KG in Q2, a gain of around 6.1%. Tighter slag availability from moderating blast furnace rates and recovering construction demand drove the H1 firming.
Higher blast furnace operating rates at integrated steel mills increased slag by-product availability relative to cement sector demand. Seasonal moderation in ready-mix concrete procurement reduced buying before the Q4 2025 construction recovery.
The global average is expected in the USD 0.088 to 0.098/KG range for H2 2026, with continued firming as slag availability stays tighter and low-carbon concrete adoption expands demand.
Germany sits highest on slag grinding electricity and processing costs, the United States and India hold a firm middle on construction and cement demand, and China prices lowest on large blast furnace slag availability.
