Question

43. The difference between maximum void ratio and minimum void ratio of a sand sample is 0,30
.
If the relative density of this sample is 66.6 % at a vojd ratio of 0.40, then the void ratio of this sample
at its loosest state will be
(a) 0.40
(6) 0.60
(c) 0.70
(d) 0.75​

Answer 1

Answer:

0.75 is the correct answer

Answer 2

Answer: (b) 0.60

Explanation:

We know

RD = (emax - e)/(emax - emin)

here RD = 0.66

emax - emin = 0.30

e = 0.40

0.66 = (emax - 0.40)/ 0.30

emax = 0.598 = 0.60
