Outline of Final Research Achievements |
In order to live in long period on the Moon or on the Mars, not only to prepare oxygen and water but also to keep concrete that is the main component of living buildings stable in years are necessary. In the living environment, carbonate water is always formed and thus the following phenomena are found to continue in series by optical high-resolution in-situ observation method. The main mineral of the concrete, Ca(CH)2, is first dissolved at the site of defects as etch pits to form the secondary mineral, vaterite, around the etch pits. The vaterite is again dissolved to form the third mineral, calcite, at the independent site of vaterite formation. The model “coupled dissolution and precipitation” proposed by Putnis can phenomenologically explain this process, but some modification was found to be necessary.
