Abstract
The current study aims in finding the utilization of Industrial waste such as copper and steel slags as a partial replacement material for sand in Sand Compaction Pile (SCP) in proportions of 5\%, 10\%, 15\%, 20\%, 30\%, and 40\% by weight. From the direct shear tests, it is observed that the angle of internal friction increases from 27.59 \& DEG; to 40.1 \& DEG; and 34.82 \& DEG; for copper and steel slags, respectively. The tests are done by installing the SCP in a soft clay in California Bearing Ratio mould and it is tested under soaked and unsoaked conditions. The optimum percentage found from the study for both the slag material is 30\%. Tests were also done by air-curing the composite soil within the mould for 7 days and water-curing the sample under soaked conditions for 4 days for the optimum replacement percentage.
