The unit weight of a soil sample is 20 kN/m3 and the water content is 18%. The dry density of the soil sample is :
Right Answer is:
16.94 kN/m3
SOLUTION
ϒd = ϒ/(1 + w)
where
ϒ = weight of solid particles of the soil mass = 20 kN/m3
w = total volume of the soil mass = 18% = 0.18
ϒd = 20/(1 + 0.18)
ϒd = 16.94 kN/m3
