EASTGAS S.R.L. is proud to announce its participation in the 17th Global Slag Conference, held on 25–26 June 2025 in Vienna. The event gathered 140 delegates from 36 countries and served as a key platform for discussing the future of metallurgical slags in the construction industry.
The focus of the conference was on effective solutions for using slags in various sectors — from cement and concrete production to fillers in rubber and polymers. Research has shown that the use of such by-products not only contributes to decarbonization and a reduced carbon footprint but also significantly improves the properties of the final products.
Special attention was paid to the potential of granulated blast furnace slag (GBFS), ground granulated blast furnace slag (GGBS) and Fly ash as sustainable components in cementitious blends.
A presentation by Hyundai Steel (South Korea) showed that GBFS enhances concrete corrosion resistance: the initiation time of reinforcement corrosion is tripled compared to traditional cement. Concrete containing GBFS aggregates showed no defects even after 12 years of exposure to marine conditions.
Nie Wenhai (Sinoma-Tianjin, China) presented advanced ultrafine grinding technologies for GBFS to 6000 cm²/g, highlighting the increase in material reactivity and performance. As the fineness increases, particle sphericity improves (up to 0.884), reactivity increases and flowability decreases.
It was also noted that combining GBFS with Fly ash improves early strength development and workability of concrete.
EASTGAS S.R.L. actively supplies the EU market with sustainable materials — blast furnace slags (GBFS, ACS) and Fly ash, supporting efforts to reduce CO₂.
We sincerely thank the organizers and participants for the high level of professionalism and discussion. Such events strengthen international cooperation and promote environmentally responsible solutions in the construction sector.
