This paper describes influence of shear stress history on unconfined compressive strength of a cement treated soil. Unconfined compression test was performed on a specimen subjected to initial undrained shear in early curing period. A specimen with 10 cm in height and 5 cm in diameter was cured under the atmosphere. Immediately after a curing period, the specimen was compressed until the axial strain attained a required value. Then a new specimen with 6 cm in height and 3 cm in diameter was cut from the compressed specimen. Subsequently the small specimen was recompressed. Main conclusions are as follows. 1) As the curing time before first compression becomes shorter, the unconfined compressive strength and the modulus of deformation at recompression increased with increasing the added axial strain at the first compression. 2) This tendency for the treated soil is different from that for untreated soil.
