Bender element (BE) is a useful seismic
tool to predict the geotechnical soil properties using
empirical correlations. However, there were uncertainties
in the correlation equations which were not
discussed in detail. In this study, the seismic data was
thoroughly investigated to improve the correlations
with the physical soil properties. Several proportions
of sand–kaolin mixtures were compacted, sheared, as
well as BE tested. The results showed curve relationships
whereas the highest seismic wave velocity and
the highest shear strength were attained at the
proportion of 40% fine content. At this point, the void
ratio, intergranular void ratio, maximum dry density,
and specific gravity were 0.43, 1.43, 1.79 g/cm3, and
2.585 respectively. In addition, a direct positive linear
relationship between the seismic wave velocity with
cohesion (c) and shear strength (s) provided highest
values of seismic velocities at 53.7 kPa and 81.7 kPa
of c and s respectively. However, the seismic wave
velocity less significant effected by the friction angle.
The paper presented 68 empirical correlation equations
between the previous parameters. The comparison
with previous researchers indicated that the
application of the empirical correlation equations
was limited to the material type (clay and sand), fine
content range (20–70%), void ratio range ([0.43),
and condition of the samples
