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.
The present research explores the strength, durability, microstructure, embodied energy, and global warming potential investigations made toward cleaner production of high-performance concrete (HPC) using a new composition. For this, various mixes were considered by replacing cement with metakaolin (MK) and silica fumes (SF) while simultaneously altering …

Large amounts of copper slag are produced every year and major fractions of it are currently disposed, not withstanding the multiple ways the material can be used. Application of the slag is often limited by the presence of hazardous elements and their leaching behavior so they can potentially pollute soil, surface water and underground water. To remove such elements …

In-depth analysis of 2192 test data sourced from the literature showed that, given all the basic material characteristics, CS/WCS can be used as the sand component for making all strength grades of concrete and giving similar (or in …
The authors of this paper systematically studied the mechanical properties and durability of concrete prepared with copper slag instead of natural aggregates. An analysis index was used to assess compressive strength, and a statistical method was used to establish a mix proportion design theory of copper slag aggregate concrete. The analysis was used to quantify …
The study revealed that, although the strength properties of all the mixes reduced with the increased temperature, the residual performance of recycled aggregate concrete is found satisfactory with the addition of copper slag up to 40% as a replacement of fine aggregate and comparable with the control concrete. The optimum performance is ...
CS is used in cement mortar production and the results revealed optimum strength efficiency up to a 5% substitution. The effects of CS combined with different silica fume …
The results obtained for concrete indicated that there is a slight increase in density of nearly 5% as copper slag content increases, whereas the workability increased significantly as copper slag ...
Performance of Copper slag and ferrous slag as partial replacement of sand in Concrete. The use of Copper Slag(CS) and Ferrous Slag (FS) in concrete provides environmental as well as economic benefits for all related industries, particularly in areas where a considerable amount of CS and FS is produced.
