| Research Abstract |
Silicate-based Surface Penetrant, which improves mechanical properties of surface concrete and provides resistivity against ingress of harmful substances, is increasingly being applied to concrete structures. However, its penetration property and improved condition of the penetrated portion, which must be important factors to estimate the long-time performance of applied concrete structure, has not been clear quantitatively yet. In this study, by evaluating its effectiveness on concrete surface quantitatively, new guideline for design and construction methods to use Silicate-based Surface Penetrant has been proposed.
