Cu-Zn and Pb slags are also used in cement manufacturing (Bijen Citation 1996; Zhang, Hama, and Na Citation 2015). In these types of slags, the morphometric complexity in the glass is typical, and semi-glass grains may behave as mineralisers. There is a direct effect of this slag on the formation of belite grains.

Cu 63 % Zn Rest % Characteristics CuZn37is the major brass alloy for the cold forming process. Even though brasses with lower Zinc content have better cold forming properties, CuZn37is the most used alloy. Reasons for this are on the one hand economical due to lower price of Zinc compared to Copper, on the other
