There is a lack of national requirements for the slag of the MSWI as the addition to the cement. For the needs of this article, the discussions were based on the requirements for the milled granulated blast furnace slag (GBFS), used as additive of type II to concrete . The standard requirements for GBFS are presented in Table 1.

Steel-slag with alkalinity greater than 1.8 is usually recommended. 2. Steel-slag can be used to produce energy-saving cement by co-grinding with OPC clinker and blastfurnace slag. In such preparations OPC clinker is about 15-30%, steel-slag around 30-40% and blastfurnace slag is around 40-50%. 3.

Copper slag is a by-product produced during smelting of copper, which is then processed into abrasive products. Typically it is composed of Ferro silicate material and oxides formed when the molten slag is quenched in cold water. This cooling process fractures the slag into coarse, angular particles making it an ideal choice in many applications.

These applications include their use as filling material in road construction [6], as additive in cement production [7], in production of railway ballasts [8] in glass production [9] and in production of thermal insulation wool [10]. ... Sarfo et al. used a pyrometallurgical method to recover metal values from copper slag and while producing …
