A soil sample having weight 23.5 gm and volume 8 cm3 consist of 2.5 cm3 of water. If the volume of soil solids in the sample is 5 cm3, the degree of saturation of soil is
If the liquid limit of the soil is 24 .5%, the plasticity index corresponding to the A-line is
A soil samples weighing 10 gm is used to determine the properties of soil. The weight of water in the sample is 4 gm and the specific gravity of soil is 2.65 . If soil is completely saturated then,
(i) The water content of the soil is 40%
(ii) The void ratio of the sample is 1.77
(iii) The porosity of the sample is 0.64
Which of the above statements are correct?
Consider a soil sample having percentage of particle passing 75-micron sieve are 64%. If the liquid limit and plastic limit of the soil is 32% and 24% respectively, the soil will be classified as
The relationship between water content (w%) and number of blows (N) in soils, as obtained from Casagrande's liquid limit device, is given by
w = 20 – log10 N
The liquid limit of the soil is
From the sieve analysis of a soil, following results are obtained.
Percentage passing through 4.75 mm sieve = 45%
Percentage passing through 75 micron sieve = 4%
Coefficient of uniformity = 5.43
Coefficient of curvature = 2.56
From the above results it can be concluded that
(i) It is a coarse grained soil.
(ii) The soil is well graded.
Which of the above statements are true?
