Two sets of cement mortars have been designed at constant water/cement ratio and consistency respectively. Densities at fresh state flexural and compressive strengths at 28 days were measured for each mortar. Capillary water absorption and carbonation depth values were determined from the cylindrical specimens after 7 years. Also the total porosities of selected specimens were measured with a mercury porosimeter in order to compare the effect of porosity on long term transportation properties of cement mortars. Results showed that it is possible to improve the fresh state and mechanical performances of cement mortars with SBR latex addition. SBR modified cement mortars also exhibited an improved impermeability in terms of both water and CO<inf>2</inf> gas penetration at the long term. The most important advantage of SBR latex addition was the improvement in CO<inf>2</inf> gas penetration resistance compared to SAR latex modified mortars. The mechanism behind this improvement is discussed with the aid of porosity analysis. © 2017 Elsevier B.V.
