Question
1. A saturated soil with a volume of 19.65cc has a mass of
36g. When the soil was dried its volume and mass were
13.50cc and 25g respectively. What is the shrinkage limit
of the soil?
2. The field unit weight of the soil sample 1s 1960 kg/m³ and
MEDR = 0.44, determine the following:
a) Specific gravity
b) Dry unit weight if water content is 15%
c) Porosity
d) Relative density
e) Saturated unit weight
f) Effective unit weight
g) Weight of water in KN that must be added per m3
for a 90%-degree saturation
h) Mass of water in kg to be added per 2.5m³ to reach
full saturation
i) If max dry unit weight is 18KN/m³, what is the
percentage of relative compaction?
j) Is it within the allowable compaction range of 95
+0.2?
