EFFECTS OF COPPER SLAG AS A REPLACEMENT FOR FINE AGGREGATE ON THE BEHAVIOR AND ULTIMATE STRENGTH OF REINFORCED CONCRETE SLENDER COLUMNS

Use of copper slag (CS) as a replacement for fine aggregate Collections (FA) in RC slender columns was experimentally investigated in this study.Twenty columns measuring 150 mm x150 mm x 2500 mm were tested for monotonic axial compression load until failure.The concrete mixture included ordinary Portland cement (OPC) cement, fine aggregate, 10 mm c
