Development of repair materials and methods for deteriorated concrete using inorganic materials.
Ceramic paint that restores the strength of deteriorated concrete.
**Surface Impregnation Material** Surface impregnation materials are penetrating protective agents used to impart specific performance to the surface of concrete, such as preventing the intrusion of factors that cause concrete deterioration, with the aim of modifying the surface layer. Although these materials are easy to apply and relatively inexpensive, there is a challenge in that there is no established application method, and good modification effects are not consistently achieved on-site. In this repair material, by cross-linking silicate with aluminum, aluminosilicate minerals are generated, and by applying the developed "Sanken Method," we have successfully increased hardness. **Sanken Method** Deteriorated concrete has enlarged capillary voids and microscopic voids within the hydration product framework, making the surface brittle and allowing water to penetrate more easily. The modification concept of the Sanken Method is to restore hardness by reinforcing the framework structure with impregnated silicate and to enhance waterproofing by sealing the capillary voids with silicates, thereby achieving effective results.
