  • Compaction

    Standard Proctor Test: Total wt. of soil used = 3 Kg No. of Layers = 3

    Empty wt. of mould = W1 =2.139 Kg

    At 6% M.C wt. of mould + Soil = W2 = 3.847 Kg

    At 9% M.C wt. of mould + Soil = W3 = 4.004 Kg

    At 12% M.C wt. of mould + Soil = W4 = 4.166 Kg

    At 15% M.C wt. of mould + Soil = W5 = 4.106 Kg

    Bulk Density = W/V

    Dry Density =( Bulk Density)/(1+M.C)

    For Saturation curve Dry Density = (GS* W)/(1+(M.C*GS))
