| Outline of Final Research Achievements |
The purpose of this study was to clarify the impact of inside/outside environment to the risk of thaumasite formation through various experiment results. As a result, it was confirmed that thaumasite tends to precipitate when dolomite is mixed in cement rather than calcite, monocarbonate is hardly formed to ettringite. These results shed light on various mechanisms of transformation of cement hydrate caused by sulfate attack.
