This study considering the waste concrete and crushed stone materials is basic material in constructing stone columns. A series of model test were run to determine the effectiveness of a single and group of stone and waste concrete columns in strengthening the soft clay. Factors such as, shape of supported footing, Stone column’s diameter and spacing were studied. The existence of a single stone column under a footing causes the Br to be increased by 19% and reduces the Sr by 50%. waste concrete column of (D=25 mm) causes the load carrying capacity of a footing to be increased by 25% over that of crushed stone column while it is increased by (45-65)% for (D=32 mm). Thus, waste concrete approved to be more effective and economical than crushed stones for constructing stone columns.
