A series of cooperative incremental loading consolidation tests of undisturbed Holocene and Pleistocene clays using the standard and small size specimens was carried out to investigate the applicability of the small size specimen. The small size specimens are φ=3cm and H=1 and 2cm. From test results, the compression curve of [φ=3cm, H=1cm] specimen is located below that of the standard specimen's [φ=6cm, H=2cm], and the consolidation yield stress and the compression index become slightly small. The applicability of test using the small [φ=3cm, H=1cm] specimen is limited to clay with the coefficient of consolidation c_v <1000cm2/d. The applicability of the test using [φ=3cm, H=2cm] specimen is higher than the test of [φ=3cm, H=1cm].
