Effect of copper slag as fine aggregate replacement in

2019-1-1  The objective of the present study is to utilize high volume copper slag (i.e. 100%) as a replacement to fine aggregate and partially replacing cement with Nano silica. The work is carried out in two phases. In the first phase, the fine aggregate is replaced with copper slag in different percentages of 20%, 40%, 60%, 80%, and 100%.
