  • Utilization of copper mine tailings as a partial substitute for cement

    In a study by Thomas et al., (2013) , copper mine tailings were used up to 60% as a replacement for cement in concrete construction with water/cement ratios of 0.4, 0.45, and 0.5; compressive strength, flexural strength, and sulfate attack resistance tests were performed on the samples, and the results of which were satisfactory.
