GGBFS : BS EN 15167-1
Ground-granulated blast-furnace slag (GGBS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. One of the most sustainable construction materials available, slag decreases greenhouse gas emissions and the use of virgin materials. The replacement of Portland cement with GGBS leads to a significant reduction of carbon dioxide gas emission. GGBS is therefore an environmentally friendly construction material which can be used to replace as much as 80% of Portland cement when used in concrete
Application:
- Production of Portland blast furnace slag cement
- Admixture of raw concrete
- Tunnels and roads construction
- Construction of dams and shore
- Agriculture
- Sewage treatment plants
- As a cementitious replacement
- Protection of environment
- And other applications.
