Utilization of copper slag in cement and concrete ...

Furthermore, it can be concluded that the utilization of copper slag in cement and concrete provides additional environmental as well as technical benefits for all related industries, particularly in areas where a considerable amount of copper slag is produced. However, the economic considerations need further evaluations in different areas.

Effect of copper slag as fine aggregate …

When sand is replaced with copper slag beyond 40% the strength of concrete was reduced and least compressive strength of 87.18 MPa is obtained when sand is replaced with 100% copper slag because the low water absorption properties of copper slag can leave excess water in concrete, which can cause excessive bleeding at higher copper slag content.
