and obtained MDD and OMC when volume of mould is 945 c.c and G = 2.7 . Also plot zero air void line.

Volume of practor mould = 945 c.c

∴ γbulk = (Mass of soil) + (Volume of soil) = 945 cc | gm/c.c

∴ γdry = {( γbulk)/(1+ω)}

w = % with content

= (G .γω)/(1+ ωG) (For saturate sample or for zero air void line)
