Abstract

In this study, two different types of latexes (Styrene Acrylate Rubber and Styrene Butadiene Rubber) at five different dosages by weight of cement have been employed in the preparation of latex modified mortars. 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.
