effect of copper slag on the self compacting concrete properties

this experimental study investigates the effects of substitution of cement with copper slag in self-compacting concrete (scc) mixtures. the rheological and mechanical properties of scc have been investigated. six concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mix) to 50%. ordinary portland cement (opc) was partially replaced by different percentages of copper slag (0, 10, 20, 30, 40 and 50%). the workability of fresh scc was measured using slump test, v-funnel flow time test, j-ring and l-box tests. compressive strength was determined at the ages of 3, 7, 14 and 28 days. compressive strength of scc decreased with the increasing in copper slag content.
