Slag vs Fly Ash: Unveiling the Power of Byproducts

Understanding Slag and Fly Ash. Before we compare slag vs fly ash, let's first understand what they are. 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.
