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 slag (GBFS) is a glassy granular product and air-cooled blast furnace slag is a predominantly crystalline, solid rock-like material.
|
GBFS is produced when molten slag is passed through high volume water sprays, breaking the slag stream into small glass droplets before crystallisation can occur.
Air-cooled blast furnace slag is formed when molten slag is cooled in pits and allowed to crystallise under atmospheric conditions.
Block Blend is a blend of GBFS and air-cooled blast furnace slag and is a coarse sand-like material consisting of angular to roughly cubical shaped particles with a characteristically vesicular structure and rough surface texture.
