An Experimental Study on Durability Evaluation of Nano Composite Hybrid Polymer Type Coatings Applied Concrete

알콕시 실란계 나노합성 Hybrid 폴리머형 코팅제를 적용한 콘크리트의 내구성능 평가에 관한 실험적 연구

In this study, durability of concrete whose surface were treated by nano-composite hybrid polymer type coatings, which can provide a barrier against the ingress of moisture or aggressive ions to concrete, is discussed. For the durability evaluation of the coated concrete, chloride ponding test, accelerating carbonation test, porosity measurement test, and the SEM test are conducted. As the result of this study, it is found that nano-composite hybrid polymer type coated concrete has a much higher resistance to the ingress of chloride ion, carbon dioxide, moisture and aggressive acid than plain concrete has.
