N2 - This study evaluates the constrained modulus (M) and the small strain shear modulus (Gmax) of cemented sand from cone tip resistance (q c). For this, a series of piezocone and bender element tests are performed in a large calibration chamber, and one-dimensional compression tests are also carried out in an oedometer cell. From the experimental results, the effects of gypsum content, relative density and vertical confining stress on cone tip resistance are investigated. After comparison of the sensitivity of cementation to the deformation moduli and cone tip resistance, the relations between cone tip resistance and the two deformation moduli are interpreted.
