Abstract
Subsidiary concrete structures such as a barrier and a side-channel suffer from rapid deterioration due to the excessive use of an de-icing in Korea. Consequently, the needs for replacement and/or repair of the structures has increased significantly, resulting in the increase of the maintenance cost. The preliminary study strongly indicates that it is necessary to improve the durability and visibility of the subsidiary structures in order to reduce the maintenance cost of the structures. Hence, the purpose of this research project is to develop a concrete with high durability by incorporating waste-glass or polymer admixture in concrete. And in order to develop concrete of high durability by utilizing waste glass, a research was focused on an effect of waste glass sludge mixing over concrete strength and durability and measurement for compression strength by each material age performed together with chloride ion penetration resistance and scaling resistance test for properties of multi-deterioration.
Key Words: Chloride ion penetration test; Multi-deterioration; Waste glass sludge; Scaling resistance test
요지
국내 콘크리트 방호벽, 측구와 같은 소구조물들은 과도한 제설제의 사용에 의해 복합열화의 피해를 받고 있으며, 구조물의 유지보수비 절감과 안전성 향상을 위해 콘크리트 소구조물의 내구성 증진이 요구되는 상황이다. 따라서 본 연구의 목적은 폐유리를 활용한 고내구성 콘크리트 개발하는 것이다. 이에 따라 폐유리를 활용한 고내구성 콘크리트 개발을 위해 폐유리 혼입에 따른 콘크리트 강도 및 내구성의 영향에 초점을 맞추었으며, 먼저, 재령별 압축강도 시험을 수행하였으며, 복합열화 특성을 확인하기 위하여 염화물 확산계수 시험과 박리저항성 시험을 실시하였다.
핵심용어: 복합열화; 박리저항성실험; 염화물 침투 실험; 폐유리 슬러지
