Effect of Stone Dust On Some Geotechnical properties Of Soil

Stone dust is a kind of solid waste material that is generated from stone crushing industry which is abundantly available. It is estimated that each crusher unit produce 15%-20% stone dust. Disposal of such wastes poses lots of geoenvironmental problems such as landfill disposal problems, health and environmental hazards. The best way to eliminate these problems is to make use such waste. Keeping this in view an experimental study was conducted on locally available soil by mixing it with Stone Dust. The effect of randomly distributed Stone Dust on MDD, OMC, Specific gravity and CBR has been discussed in this paper. The percentage of stone dust by dry weight of soil was taken as 10%, 20%, 30%, 40% and 50%.The first series of compaction, specific gravity and CBR tests were conducted on the soil and the same tests were conducted in the second series on soil samples mixed with stone dust. Laboratory experiments favorably suggest that mixing stone dust with soil would be effective in improving soil properties.
