| Outline of Final Research Achievements |
In order to develop a method to evaluate the degradation factor penetration prevention property of silicate type surface penetrants, the Vickers hardness test was conducted by utilizing the increase in the strength of the reaction part of the silicate type surface penetrants. Then, it was examined whether the area of hardness increment and modification depth could be deterrent to deterioration factor penetration.
Water absorption inhibition by the water absorption test and the inhibition by the salt penetration test were evaluated. As a result, this index has shown the possibility of being applicable as a deterioration factor penetration prevention property of the silicate type surface penetrants. However, as the issues were clarified, the need to consider was also clarified.
