Abstract: This research paper present an experimental investigation of the result of using copper slag (CS) asfine aggregate for replacement of river sand in self-compacting concrete (SCC).Totally Eleven concrete mix proportion are prepared with various mix ratio of copper slag varies from 0% (for the control mix ratio) to 100%. Test methods used to study the characteristics of fresh concrete were slump test, U-tube, V-funnel and L-box. Concrete mix are tested for workability, density, durability, compressive strength and tensile strength. The results shows there is a lessincrease in high performance concretedensity of 3% with therise of copper slag as fine aggregate, whereas the workability increase quickly with increases in CS percentage. In adding up to 40% of copper slag as fine aggregate replacement yielded comparable strength with that of the control mix. However, further additions of CS cause reduction in the high strength due to an increase of water content in the mix proportions. Mixes with 90 and 100% copper slag replacement gave the low compressive strength values. Therefore, it is recommended 50 weight% of CS can used as replacement of sand as fine aggregate in order to acquire high performance.
