CIVL 1101 - Assignment #8

 Name: ________________________


"Out of clutter, find simplicity; from discord, find harmony; in the middle of difficulty, lies opportunity." - Albert Einstein, The Three Rules of Work
 

The purpose of this assignment is twofold: first, to measure particle size characteristics of materials that will be used in our next project; and second, to become familiar with the ASCE author-date citation system.

You must hand in a copy of the cover sheet for the assignment and printouts Parts 1-3. There are no Canvas submissions for this assignment.

Part 1: The following are the results of a sieve analysis:


Sieve Number

Mass of soil retained
on each sieve (g)

Percent retained
on each sieve (%)

Cumulative percent
retained on each sieve (%)

Percent
finer (%)

4 0      
10 41.2      
20 55.1      
40 80.0      
60 91.6      
100 60.5      
200 35.6      
Pan 21.5      

Determine: (a) the percent finer for each sieve and plot the particle-size distribution curve; (b) estimate D10, D30, and D60 from the particle-size distribution curve; (c) the effective size; (d) the uniformity coefficient, Cu; and (e) the coefficient of gradation, Cc.

Part 2: For the sieve analysis performed in laboratory determine: (a) the percent finer for each sieve and plot the particle-size distribution curve; (b) estimate D10, D30, and D60 from the particle-size distribution curve; (c) the effective size; (d) the uniformity coefficient, Cu; and (e) the coefficient of gradation, Cc. If you were unable to get data in lab, use the following data for anthracite.


Sieve Number

Mass of soil retained
on each sieve (g)

Percent retained
on each sieve (%)

Cumulative percent
retained on each sieve (%)

Percent
finer (%)

4 0.1      
8 0.3      
16 378.9      
30 104.9      
50 26.4      
100 0.2      
Pan 0.2      

Part 3: Follow ASCE citation guidelines (class slides) to prepare a reference page comprised of the following sources.

Part 4: Read Chapter 8 in the Strategies for Creative Problem Solving by Fogler and LeBlanc.
