Abstract :
Some geotechnical properties of soils around
Eziobodo, Southeastern Nigeria was investigated using
standard methods. Samples were obtained at three
locations, Eziobodo, Ihiagwa and Obinze. The properties
determined were particle size analysis, compaction (bulk
density, dry density, natural moisture content, maximum
dry density and optimum moisture content) and
Atterberg limits (liquid limit, plastic limit and plasticity
index). The sieve analysis shows that the samples are
mainly sandy particles. The liquid limit values for the
three locations (Eziobodo, Ihiagwa and Obinze) were 10,
46, and 47% respectively, while the plastic limit were 26,
21, 26.81 % respectively with plasticity index PI of -16,
25, and 20.19 % respectively. The natural moisture
content of the samples were 10.3, 9.8 and 7.9%
respectively. The bulk density values were 1.76, 1.69, and
1.66 mg/m3
respectively while the dry density values
were 1.40, 1.35, and 1.31 mg/m3
respectively. The
maximum dry density for the locations were 1.54, 1.43,
and 1.41 mg/m3 while the values for the optimum
moisture content were 24, 27.5 and 26.5% respectively.
Because of their non-plastic behavior, high percentage of
sand content, most of the sediments have low swelling
potential; have high collapsibility potential, loses
strength upon saturation and eventually susceptible to
erosion.
