Apr 21, 2021· copper slag increased compressive and tensile strength by 11% and 12%, respectively. The increase of the replacement percentage of natural aggregate with copper slag gradually increased concrete density [19]. Recently, copper slag has been used as a replacement for cement, e.g., in the production of cement clinker [20,21], and as a substitute ...
specimens is maximum at 40% of replacement of copper slag for 28days curing. 6. The flexural strength of copper slag concrete is also maximum at 40% replacement of copper slag for 28 days of curing. So the replacement of 20% to 40% of copper slag is generally useful for better strength values in M30 grade of concrete. REFERENCES

Partial replacement of copper slag in fine aggregate and cement reduces the cost of making concrete. Replacement of copper slag ( replacement with sand)increases the self weight of concrete specimens to the maximum of 15-18%. The initial and final setting time of copper slag admixed concrete is higher than control concrete.
