CHAPTER 2
INDEX AND CLASSIFICATION PROPERTIES OF SOILS
2-1. From memory, draw a phase diagram (like Fig. 2.2, but don’t look first!). The “phases” have
a Volume side and Mass side. Label all the parts.
SOLUTION: Refer to Figure 2.2.
2-2. From memory, write out the definitions for water content, void ratio, dry density, wet or moist
density, and saturated density.
SOLUTION: Refer to Section 2.2.
2-3. Assuming a value of
ρs = 2.7 Mg/m3 , take the range of saturated density in Table 2.1 for the
six soil types and calculate/estimate the range in void ratios that one might expect for these soils.
SOLUTION: Create a spreadsheet using input values from Table 2.1 and Eq. 2.18.
ρ' - min ρ' - max emax e min
(Mg/m 3 ) (Mg/m 3 )
0.9 1.4 0.89 0.21
0.4 1.1 3.25 0.55
1.1 1.4 0.55 0.21
0.9 1.2 0.89 0.42
0.0 0.1 ∞ 16.00
0.3 0.8 4.67 1.13
(Given) (see Eq. 2.18)
