When studying the mechanical behavior of hydrated binders, it is necessary to prevent hydration contraction tensile failure in order to properly characterize the mechanical properties of the material. This is regulated by standards for cement testing, however for the case of water-cement-bentonite mixtures the influence of standard sand is not thoroughly studied. Since the hydration shrinkage and water suction is different for cement and bentonite, a range of eleven combinations of water-cement-bentonite were used at four sand percentages. The paper documented this influence ranging from a lower limit for which contraction cracking occurs up to an upper limit for which the presence of sand favorably interferes with the binder, the material being transformed from a binder paste into a mortar. It is documented the range of sand composition for which the variation of sand content prevents contraction, yet preserves binder properties. The laboratory testing consisted of viscosity evaluation during samples preparation, permeability and monoaxial compressive strength on samples cured in open atmosphere for 28 days.
