of the concrete with copper slag is lower than the control (no copper slag) mixes [1726–, 2031, ]. Very few papers assessed workability of the copper-slag concrete. Gener-ally it was found that copper slag may increase workabil-ity of concrete mixes (e.g. [1731–]) but most of these 20, papers used superplasticizers to enhance workability of
