Abstract

Recently, concrete facility as advanced water treatment facilities is extending in the water treatment facilities according to raise awareness of pure drinking water and delicious water. For this reason, it is increased to the necessity need to make the standard and the development of waterproofing and anti-corrosion materials for concrete structures applied water treatment tank. So, related research has become active recently. However, as the limit of research focused on durability improvement of top coating material, it is insufficient to study on the adhesion strength between the concrete surface and primer. Therefore, there is to confirm the adhesion of between concrete surface and the three primers used as anti-corrosion waterproofing materials, and to investigate the properties of adhesion strength according to the condition such as dry condition, wet condition, and water pressure condition of the concrete surface in this study.

최근 '먹는 물'에 대한 인식이 높아지고 양질의 물에 대한 요구가 이어짐에 따라 정수처리 시설은 수처리 시설을 확대하고 있다. 이에 따라 수처리시설에 적용되는 콘크리트 구조물 내부 방수 방식재의 개발 및 기준 마련의 필요성이 높아지면서 최근 활발한 연구가 진행 중이다. 하지만, 주로 상도의 내구성 향상에 집중된 연구의 한계성으로 콘크리트 표면과 하도 (프라이머)와의 부착력에 대한 연구가 부족한 실정이다. 이에 본 연구에서는 수처리시설의 내부 방수 방식재로서 사용되는 프라이머와 콘크리트 표면간의 부착력을 확인하고, 콘크리트 표면 상태 (건조 상태, 습윤 상태, 수압상태)에 따른 부착강도 및 특성에 대하여 알아보고자 한다.
