Textbook Problem

The following are the results of a sieve analysis.

images

a. Determine the percent finer than each sieve and plot a grain-size distribution curve.

b. Determine D10, D30, and D60 for each soil.

c. Calculate the uniformity coefficient Cu.

d. Calculate the coefficient of gradation Cc.

(a)

To determine

Calculate the percent finer than each sieve and plot a grain-size distribution curve.

Explanation

Calculate the total mass of the soil (M) using the relation.

M=M1+M2++Mn+Mp

Here, M1+M2++Mn is mass of soil retain in corresponding sieve number and Mp is the mass of soil retained in the pan.

Refer the given table for mass of soil retained in each sieve no.

Calculate the total mass of the soil as follows:

M=0+18.5+53.2+90.5+81.8+92.2+58.5+26.5=421.2g

Calculate the cumulative mass retained on each sieve using the relation.

For mass 1 (M1):

M1=M1

For mass 2 (M2):

M2=M1+M2=0g+18.5g=18.5g

For mass 3 (M3):

M3=M1+M2+M3=0g+18

(b)

To determine

Calculate D10,D30, and D60 for each soil.

(c)

To determine

Calculate the uniformity coefficient.

(d)

To determine

Calculate the coefficient of gradation.
