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
