The cement and slag materials market continues to show growing interest in Air‑cooled blast furnace slag (ACS) and Granulated blast furnace slag (GBFS). These materials are becoming essential in decarbonisation strategies, clinker reduction and improving the efficiency of cement production.
Buzzi reports rising demand for slag-based additives
The Italian group Buzzi has published its consolidated financial results for 2025, showing steady growth in the cement and slag materials segment. The company notes that demand for GBFS continues to increase as concrete producers shift towards low‑carbon mixes.
The report highlights that slag products are becoming strategically important for the cement sector, as they significantly reduce clinker content and lower CO₂ emissions. This aligns with the broader trend of increasing the share of secondary materials and adopting more sustainable production technologies.
Vicat receives EU funding for CO₂ capture technologies
The French group Vicat has announced that it received an EU Innovation Fund grant for the VAIA project, aimed at implementing CO₂ capture and storage (CCS) technologies.
The project directly influences the GBFS and ACS market, as the modernisation of cement plants and the adoption of CCS solutions stimulate demand for secondary materials that help reduce the carbon footprint of cement products.
Such investments create favourable conditions for expanding the use of slag materials in cement formulations, especially in regions actively pursuing decarbonisation.
Growing role of circular materials
Cement producers continue integrating GBFS and ACS into their production processes, increasing the share of secondary materials in their formulations. This not only reduces CO₂ emissions but also improves durability and performance characteristics of cement mixes.
The market is clearly moving toward circularity and low‑carbon production, where slag materials play a key role in the modernisation of the cement industry.
