Compaction Calculation Formulas

Max Dry Density (Proctor) Pp = Given

Sand Density Ps = Given

Weight Of Cone + Sand - Before Wcal1 = Given

Weight Of Cone + Sand - After Wcal2 = Given

Weight Of Sand Fill Cone (Wc) = Wcal1 - Wcal2

Cone + Sand – Before Wb = Given OR Wb = Wcal2

Cone + Sand – After Wa = Given

Weight Of Wet Soil Ws = Given

Moisture Content MC = Given

Weight Of Sand Fill Hole (Wh) = Wb - Wa - Wc

Volume Of Hole (Vh) = Wh / Ps

Density Of Wet Sample (Pw) = Ws / Vh

Density Of Dry Sample (Pd) = Pw / (1 + MC / 100)

Compaction = (Pd * 100) / Pp
