Abstract

In this study, the change of getechnical properties of sand due to cementation was investigated by undrained triaxial test of isotropicallv consolidated sample. For inducing the cementation, $5\sim20%$(sand weight) gypsum were included in the sand and cured in the mold under the overburden pressure 55kPa. The yielding strength and stiffness of cemented sand were increased and also the aspects of effective pore water pressure were changed as the degree of cementation and the relative density. Generally the degree of cementation exerted more influence on the behavior of cemented sand than the relative density.
