Research corrosion of cements with a new hydraulic additive

Based on the above studies, following conclusions can be made: The introduction of hydraulic additives into Portland cements increases their sulfate resistance, especially when have higher C 3 A content. Cements with 30% tuffite give better strength than those 20% tuffite. least aggressive for pozzolanic are 5% Na2SO 4 solution, most is 3% MgSO in which were more resistant pure cements, agreement data other researchers. For sulfate-resistant cement maximum content original increased up to 8%.
