Based on the above studies, the following conclusions can be made: The introduction of hydraulic additives into Portland cements increases their sulfate resistance, especially when cements have higher C3A content. Cements with 30% tuffite give better strength than those with 20% tuffite. The least aggressive for pozzolanic Portland cements are 5% Na2SO4 solution, the most aggressive is 3% MgSO4 solution, in which cements with hydraulic additives were more resistant than pure Portland cements, which is in agreement with the data of other researchers. For sulfate-resistant pozzolanic Portland cement maximum C3A content in the original Portland cement can be increased up to 8%.
Key words: Hydraulic additives / tuffite / corrosion resistance / frost resistance / weatherability / aggressive mortar / strength
