چکیده مقاله:

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.
