1. Introduction. Copper slag (CS) is a by-product of the copper smelting process and is one of the nonferrous metal residues. CS is mainly composed of Fe 2 O 3, SiO 2, and a small number of metallic elements [1,2,3].CS holds great promise for resource utilization of building materials, particularly in cement-based materials (CBMs), which …
