The authors have prepared a significant
investigation in swelling behavior of expansive clay.
The lateral swelling potential obtained from
modified oedometer test was especially interesting.
Discussant used the term of swelling potential to
represent both strain and swelling pressure. The
effect of three different initial water contents, which
is 20%, 25%, and 30%, on swelling potential has been
studied. The specimens were prepared at similar
densities. The lateral swelling potential has been
measured from the installed strain gauges. However,
installation of the strain gauges and procedure of the
test were not clearly informed.
