Abstract

Currently, the most commonly used decontamination agent in the country is calcium chloride, and the use of decontamination agents nationwide is on the rise due to climate change in the country. The deicing agent, aimed at deicing snow, is sprayed and the chloride is frozen and thawed by the dissolved surface water, causing various damages such as deterioration to the concrete. Therefore, in this study, the reactive urethane polymer was manufactured to coat concrete surface protection material, which is a method that prevents moisture from externally penetrating by applying to concrete surfaces, and the mixing agent was selected through the size control of molecules and surface modification, and the properties of penetrant stiffening agents and the application method of concrete was evaluated.

현재 국내에서 가장 보편적으로 사용되고 있는 제설제는 염화칼슘이며, 우리나라의 기후 변화에 따라 전국적으로 제설제의 사용량이 증가하고 있는 추세이다. 제설 제빙을 목적으로 하는 제설제는 살포되어 염화물이 용해된 노면수에 의해 동결융해 작용으로 콘크리트에 열화 등의 다양한 피해를 주고 있다. 따라서 본 연구에서는, 콘크리트 표면에 도포하여 외부에서 침투하는 수분을 차단하는 방식인 콘크리트 표면 보호재를 실리콘 기반으로 한 콘크리트 미세기공을 코팅할 수 있도록 반응형 우레탄 폴리머를 제조하여, 분자의 크기 제어와 표면 개질을 통해 혼화제를 선정하여, 콘크리트 적용하였고 침투강화제의 특성 및 도포방법에 따른 콘크리트 기초 물성을 평가하였다.
