A cement stabilized soil may be subjected to undrained shearing under an in-situ stress condition, so that a cementation is formed and destroyed simultaneously. Unconfined compression test was performed on a specimen in order to precompression in early curing period. Immediately after the precompressed specimen was cured under the atomosphere or an overburden pressure, the specimen was again compressed in unconfined compression test. Main conclusions are as follows. As curing time up to precompression became shorter, the unconfined compressive strength was increased. On the contrary, as the curing time became longer, the strength was decreased. When the overburden pressure was considerably high, a specimen subjected to any shear history caused a consolidation settlement and an increase of unconfined compressive strength. Anincrease rate of unconfined compressive strength of specimen with shear history was very low as compared to that without shear history.
