Consider the following points related to unified soil classification system:

(i) The soil particles above 4.75 mm termed as coarse grained soil.

(ii) The soil particle below 4.75 mm are fine grained soil.

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

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?
