Slag: From Byproduct to Valuable Construction Material

· Slag: From Byproduct to Valuable Construction Material. By Stephen Dietz Slag is a byproduct of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process ...
