the maximum shear strength of cementedreinforcedsand as function of cement content (case of a water content ω = 10%).
(coefficient of determination R 2 = 0.92, 0.98 and 0.98 for the three normal stresses σn = 100, 200 and 400 kPa, respectively).
3.3 Cement content effect on the mechanical characteristics
Although a curved rupture envelope is expected for the sand-cement mixtures under study, by a linear regression between the shear stresses and the normal stresses applied to the samples at a given shear displacement; to determine the shear
