GBFS

Granulated Blast Furnace Slag
 
Products > Cementitious Materials > Granulated Blast Furnace Slag (GBFS)
 

Blast-furnace slag is the nonmetallic product consisting essentially of silicates and aluminosilicates of calcium and other bases that develop in a molten condition simultaneously with iron in a blast furnace. Granulated slag is the glassy, granular material formed when molten slag is rapidly chilled. GBFS is formed when molten blast furnace slag (BFS) is rapidly quenched from the furnace, rather than left to slowly solidify by air-cooling. On casual examination, GBFS would pass for river sand, with a top size of about 6mm. It typically has a density of about 60 - 70% of natural sand.

 

GBFS may be used without further processing as a construction sand, soil/pavement stabilising media or grit-blasting material. Slags are classified into three grades (80, 100, and 120) based on their respective mortar strengths when blended with an equal mass of Portland cement (ASTM C989).

 

Renelux supplies the cement industry with GBFS & GGBFS which are mainly sourced from India and Microfine GGBS (Substitute to micro silica), a new generation supplementary cementitious material, that is sourced from India.

 

 
 
 
Applications
 
As a general purpose construction sand in civil engineering applications
As an ideal select fill behind reinforced earth wall construction. Within a relatively short time, the pozzolanic properties of granulate cause it to set and form a solid block
As a source of alumina and silica in glass manufacture
As a stabilising agent in road construction. There have also been examples where only granulate has been used as pavement material. Pavements now exist where granulate has been used in conjunction with steel slag to form very heavy-duty pavements.
As a grit-blasting medium: granulate is particularly suitable for soft metals such as aluminium where a light etch is required
