pore water which is practically incompressible. Note that excess pore water pressure is
generated in consequence of incompressibility of pore water upon negative dilatancy of
sand.
To understand the mechanical behavior of solidified colloidal silica, a series of uncon-
fined compression tests were carried out. Figure15.35 shows a specimen prior to test;
the sample measured 7cm in height, 4.7cm in diameter, and 129g in weight. The tested
