In this study, a series of drained triaxial tests were performed in order to examine the effect of cementation on the shear behavior of granular soil. It was observed that the brittle nature and dilative tendency of granular soil is dominant under a low confining stress level, while high confining stress results in a contractive behavior despite the strong cementation bond. Based on experimental results, an idealized concept is suggested to define the shear strength of cemented sand in three distinctive zones: the cementation control zone with a constant cohesion intercept at a low confining stress level, the transition zone in which the cohesion intercept is gradually reduced after a breaking point, and the stress control zone with almost zero cohesion intercept due to breakage of cementation bonds at a high confining stress level. It was shown that the sitting pressures during cementation have little effect on the strength parameters of cemented sand, while the increase of gypsum content and relative density, and the decrease of particle size, result in an increase of the cohesion intercept and the breaking point. In addition, the prediction equations for the shear strength and cohesion intercept in the cementation control zone and the transition zone are suggested from the analytical and experimental interpretation.
