Uses Of Air Cooled Slag In Bricks
Furnace Slag
Pelletized blast-furnace slag resulted from cooled blast-furnace slag. It has a vesicular texture and it is used as a lightweight aggregate and finely grounded as cementitious material. Air-cooled blast-furnace slag is naturally cooled with moderate sprinkling. The crystallized slag, after crushing, sieving, and removing magnetic matter, can be ...
