An experimental study on durability evaluation of the concrete applied nano level inorganic polymer based coatings

나노합성 무기질 폴리머계 표면처리제를 적용한 콘크리트의 내구성능 평가에 관한 실험적 연구

In this study, durability of the nano-level inorganic polymer based coatings which can provide a barrier against the ingress of moisture or aggressive ions to concrete is discussed. For the durability evaluation of the coatings, chloride penetration test, accelerating carbonation test, freezing and thawing test, and sulfate ponding test are conducted. As the result of this study, concrete applied nano-level inorganic polymer based coatings has a much higher resistance to the ingress of chloride ion, carbon dioxide, moisture and aggressive acid than plain concrete and epoxy resin based paint by means of crosslinking three-dimensional structure with concrete structure.
