실란계 흡수방지재와 규산계 흡수방지재의 콘크리트 도포에 따른 염화이온 침투 및 탄산화 저항성 평가에 관한 실험적 연구

Abstract

An experiment was conducted using an absorption preventive material as a solution to the penetration of CaCl2 and carbonation of domestic concrete. In the experiment, chloride ion penetration resistance and carbonation resistance were evaluated. As a result, it was confirmed that silane-based absorption protection materials had better carbonation resistance than silicate-based absorption protection materials. During the chloride ion penetration resistance experiment, no current was applied inside the concrete coated with a silane-based absorption preventing material. It is judged to have a characteristic of simultaneously suppressing moisture penetration into the concrete and chloride ions penetration due to the high water repellency of the absorption preventing material. Through this experiment, it was found that silane-based absorption protection materials have better quality performance than silicate-based absorption protection materials.
