REPLACEMENT OF COPPER SLAG WITH FINE AGGREGATE
The mix design of M25 grade of concrete gives HPC concrete when replacement of copper slag is 50% 2 In this case we observed that Copper slag behaves like river sand 3 It is observed that when increasing percentage replacement of fine aggregate by Copper slag the unit weight of concrete is gradually increases REFERENCES 1The results are presented above The optimum value which provided the best performance was at 50% addition of copper slag for compressive strength The concrete was prepared for the M20 grade concrete with partial replacement of fine aggregate by copper slag with various percentages of (0%, 5%, 10%, 20%, 30%, 40% and 50%)(PDF) Partial Replacement of Copper Slag as Fine copper slag Fig7 Comparison of Flexural Strength of Beam IV CONCLUSION The concrete was prepared for the M 25 grade concrete with partial replacement of fine aggregate by copper slag with various percentages of 0%, 10%, 15% and 20% The specimens were casted for 7days, 14 days and 28 days then tested The results are presented abovePartial Replacement of Copper Slag as Fine Aggregate
