Abstract

In (5 ± 1)°C, 5% in mass MgSO₄ corrosion solution, the visual appearance, strength and composition analysis of cement mortars added with different functional chemical admixtures (shrinkage-reducing agent, hardening accelerator, crystal resistance agent) and limestone powder were researched at different storage times. The results indicated that after corroded for 360 days, the thaumasite crystal appeared in all cement mortars added with different functional chemical admixtures. It showed that the functional chemical admixtures used in this experimentation could not solve TSA problem, but some of them (except crystal resistance agent) could delay TSA development at early period (210 days).
