A Study on the Surface-Treatment Agent as Concrete Repair Materials

콘크리트 보수재료로서 도포형 표면강화물질 검토

We examined the silicate-based material to develop the surface-treatment agent, which would be used to restore performance of the deteriorated concrete and to inhibit corrosion of the reinforcing bar. As a part of the study, we carried out experiments of the penetration and strengthening properties of concrete treated by the considering agent. The variables of experiment, were the type of silicates, the ratio of distilled water-silicate, the usage of surface-strengthening material, and the usage of biochemical material. The penetrating ability of concrete is assessed by viscosity and surface tension. Also assessments of strengthening effects of concrete are performed on compressive strength, absorption, and water permeability tests.
