Abstract

The strength, expansive rate, visual appearance and hydrate of various cements at different hydration ages were studied by immersing the mortar specimens in 5% (in mass) MgSO₄ corrosion solution at (5±1)°C. The cements used for mortar specimens were made of ordinary portland cement (OPC), rapid hardening sulphoaluminate cement (SAC), sulfate resistant portland cement (SRC), and OPC-SAC composite cement (PAC), with 30% (in mass) limestone powders respectively. The study shows that the resistance to thaumasite sulfate attack (TSA) are different for the variety of cement, SRC can't resist TSA damage effectuall, PAC exhibits a good resistance to the TSA.
