| Zusammenfassung: | According to the present invention, by using a blast furnace slag cement with excellent durability and an admixture with excellent acid resistance, chemical resistance, and durability to repair a cross-sectional area damaged by acid or sulfuric acid, it is possible to prevent the loss of strength inside the concrete due to chemical erosion and the occurrence of expansion and cracking by producing ettringite, and thus possible for Co^2 reduction by utilizing industrial by-products and providing an eco-friendly cross-sectional recovery method.
본 발명에 따르면 콘크리트 구조물이 산이나 황산에 의해 손상된 단면 부위를 보수하기 위해 내구성이 우수한 고로슬래그 시멘트와 내산성 및 내화학성, 내구성이 우수한 혼화재를 사용함으로써, 화학적 침식으로 콘크리트 내부의 강도 손실을 일으키는 것과 에트린자이트를 생성하여 팽창과균열을 일으키는 것을 방지할 수 있으며 산업부산물 활용을 통한 Co²저감 및 친환경적 단면복구 공법을 제공하고 있다. |
