concrete increases proportionally up to 40% replacement of sand with copper slag. Al-Jabri et al. (2009) investigated the performance of high strength concrete (M80) made with copper slag as a fine aggregate and recommended that 40% replacement of sand produces good quality high performance concrete.

Also Table 2 shows that there is general slight increase in the density of high performance concrete with the increase of copper slag quantity. The density of concrete was increased by almost 5%. This is mainly due to the higher specific gravity of copper slag which was 3.4 compared with sand which has a specific gravity of 2.77. 4.3.

Fayalite is the main phase of copper slag and a type of Fe silicate glass that is composed of a polymerized network of silicate tetrahedrons, in which SiO 2 and FeO are generally considered as network formers and modifiers, respectively. The structure of fayalite is shown in Fig. 13 [107].In iron silicate glass, O 2− exists in the form of bridging and non …
