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.
Granulated blast furnace (GBF) slag is a glassy, granular material.
|
Molten slag is passed through high volume water sprays, breaking the slag stream up into small droplets and cooling them so quickly that crystallisation is suppressed.
Cement Grade Granulate is a coarse sand-like material with a porous, amorphous structure and ranging from white to golden brown in colour.
