Moisture and water transfer in concrete can be considered as a significant threat to the durability of concrete. Damp-proofing admixtures like calcium stearate (CS) can provide a water-repellent layer along the capillary pores and as a result, water and moisture transfer in concrete can be restricted by means of this layer. Accordingly, this research studies the effects of CS on the properties fresh and hardened self-consolidating concrete. The evaluation of fresh concrete properties demonstrates the density of fresh concrete, passing and filling ability were reduced due to the incorporation of CS. Moreover, the reduction in the density and compressive strength of the hardened were observed as the major impacts of CS on the mechanical properties. In fact, the last-mentioned parameters were decreased by respectively 4% and 30% due to the inclusion of 7kg/m3 CS. Furthermore, utilizing CS cannot be taken into account as a constructive approach to improve the durability characteristics under non-hydrostatic condition. As no considerable improvement can be detected in the results of electrical resistivity and rapid chloride migration tests. Eventually, CS enhanced the permeability of the durability of the hardened concrete under non-hydrostatic condition. To be more precise, the addition of 7kg/m3 of CS decreased the final depth of capillary water absorption, short and long-term water absorption by respectively 60%, 65%, and 15%.
