摘要：

The compositions of the solutions at the four invariant points that define the AFt equilibrium surface, have been calculated at 25-degrees-C with and without sodium ions. The results indicate that AFt is stable over a large range of sulphate concentration depending on both the calcium and aluminium concentrations. The presence of sodium modifies the AFt stability domain but it remains stable even at high sodium concentrations.
