Shear strength studies on soil-quarry dust mixtures

About 20-25% of the total production in each crusher unit is left out as the waste material-quarry dust. Bulk utilization of this waste material is possible through geotechnical applications like embankments, back-fill material, sub-base material and the like. It becomes a useful additive to the natural soil to improve its strength characteristics.
