Hardening of stabilized soils with cement and lime has been the subject of much investigation [1]. In this study it has been endeavored to experimentally investigate the mechanical behavior of stabilized red-marl with ordinary Portland cement. Various tests were carried out on cylindrical and prismatic, compacted specimens to evaluate tensile and compressive yield loads and modulus of elasticity of the material .The effect of cement content and curing time was studied on mechanical characteristics as well as parameters of the failure criterion. Sample with cement contents of 4, 6, 8 and 10% and curing times of 2 and 4 weeks were prepared at constant densities and moisture content.
