Question
A fully saturated clay sample has a mass of 1526 grams.
After oven-drying, its mass was reduced to 1053 grams.
The specific gravity of soil particles is 2.7. Calculate the
porosity in percent (%).
Select one:
a. 43.19
b. 54.81
C. 25.17
d. 32.52
A measure of density of a compacted fills as part of the
specification requirement was performed by digging a
hole in the soil, weighing the extracted sil and
measuring the volume of the hole. The soil (moist)
weighed 770 grams. 420 g of the dried soil was poured
into a vessel in a very loose state. Its volume was
subsequently determined to be 280 cm. The same 410
grams of dried soil was then vibrated and tamped to a
volume of 220 cm. If the specific gravity of the soil
sample is 2.7, compute the void ratio of the soil in in-situ
state.
Select one:
a. 0.59
b. 0.68
c. 0.36
d. 0.47
