Abstract

From our previous studies, it has reported that the brittle behaviors of cement treated clay was improved to ductility by adding some tire chips in unconfined compressive test and tri-axial compressive test. Because tire chips are elastic material, it has been expected that it was prevented from generating and growing cracks by elastic reaction which generated from tire chips during compressive shearing.<br>In this study, it was investigated and experimented that the relation between deformation and changing in permeability of cement treated clay with added tire chips under deformation. Because it was paid attentions to a low permeability of cement treated clay at no-deformation, and the effect of improving ductility by adding tire chips. From these studies, it was obtained that, during deformation, the permeability of cement treated clay without adding tire chips was changed to high, but also, in the case of adding tire chips, the changing permeability was very small.
