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 …
Each specimen tested on the compressive strength, water absorption and density of the concrete. Findings: The test results show that the compressive strength increases with the increase of the copper slag content and a marginal change is observed with the decrease in strength gain as there is increase in the copper slag content.
In this paper, the influence of heating up to 400°C on properties of the self-compacting concrete containing recycled copper slag fine aggregate was investigated. The …

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.
Abstract: The present investigationassesses the incorporation of copper slag in concrete.
