Slag vs Fly Ash: Unveiling the Power of Byproducts
Slag is a byproduct that results from the smelting process of various ores, such as iron, copper, and lead. When these ores are heated to extract the desired metal, slag is formed as molten, which is later cooled and solidified. On the other hand, fly ash is a byproduct of burning pulverized coal in power plants.
