Modified 80/20 Slag Roadbase |
Blast furnace slag is the non-metallic product consisting essentially of silicates and aluminosilicates of calcium and other bases, that is developed in a molten condition simultaneously with iron in a blast furnace.
Air-cooled blast furnace slag is a
predominantly crystalline, solid rock-like
material whereas granulated blast
furnace slag is a glassy, granular product.
|
Air-cooled slag is dug, crushed, screened and blended with granulated slag in 80/20 volumetric proportions and modified with a stabilising agent.
