Sulfate resistance of plain and blended cements under different sulfate environments is experimentally investigated in this paper. A total of eight different cements were used for the production of mortar specimens. All specimens were immersed in two different solutions: a 5% Na2SO4 solution and a 2.5%Na2SO4 + 2.5% MgSO4 solution. Length change measurements were taken for a time period of two years. At the age of 2 years, compressive strength as well as flexural strength measurements were taken for all mixtures. Results indicate that fly ash blended cements have a very good performance in both curing environments.
