Question

The natural water content of a saturated quartz sand is 20%; its voids ratio is likely to be about 0.55.

Select one:

True

False

Answer 1

Ans : False, Because according to question , we have water content ,w = 20% , void ratio , e = 0.55

For calculating void ratio , the specific gravity for saturated quartz sand is = 2.67 ( Not given )

FORMULA :

Where e = void ratio

w = water content

Gs = specific gravity

S = saturated = 1

which is not equal to 0.55

Therefore , for natural water content of a saturated quartz sand is 20% , the void ratio is 0.534 not 0.55 .
