Ayano and Sakata explored how copper slag affected the drying time of cement (2002). The insoluble residue at 0.15 mm was found to be easily removed by simply washing the slag. This research demonstrated that the setting time of cement was affected by the particle size of copper slag, with smaller particles creating a longer delay.

In this study, basalt aggregate with a maximum size of 4 mm was used. A sieve analysis of the basalt and QCS-aggregate can be seen in Fig. 1.Before using the basalt in concrete, the water absorption of this material was investigated according to Ref. [31].The water absorption of basalt and QCS-aggregate is shown in Fig. 2.. Download : Download high-res …
Key takeaway: 'Copper slag and washed copper slag can be used as sand in concrete, providing similar or better performance than natural sand, while reducing water demand and achieving strength gains.'
This paper reports the results of an experimental study on the high performance concrete made with copper slag as fine aggregate.

Copper slag is a derivative product obtained from matte smelting and refining of copper [25].It is a non-reactive and non-hazardous material whose size is similar to the NFA and it can be used as a NFA material in concrete with proper processing (Fig. 3).The physical properties of CS such as surface texture, particle shape and size, fineness, and specific …
