Question

1.      Data points from a std moisture density test on a fine grained soil are given in the following table:

Water Content                                       Total Density

(%)                                                       (pcf) _______                           

20.0                                                      99.6

23.1                                                      105.9

25.6                                                      111.2   

28.5                                                      115.1

31.3                                                      113.4

34.0                                                      111.5

Compacted one cylinder of the soil describes above table to compare the new results with shown. The data obtained included a water content of 32.5% and a total density of 121.9 pcf. Comment on these new findings??

Please provide complete step by step solution and explanation. Thank you!!

Explanation / Answer

FOR THE SAME WATER CONTENT IN THE LISTED CASE TOTAL DENSITY ACHIEVED WAS AROUND 112 pcf

SO THE 121.9 pcf OF TOTAL DENSITY MAY BE DUE TO THE HIGHER AMOUNT OF ENERGY EMPLOYED FOR COMPACTION OF THE SAME AMOUNT OF SOIL.
