요약
철근콘크리트구조물에서 발생하는 화재는 중성화를 촉진시켜 철근콘크리트구조물의 내구성을 현저하게 저하시키는 원인이 된다. 그러나 국내의 경우 화재로 인해 중성화가 촉진된 철근콘크리트구조물의 내구성 회복을 위한 연구 및 기술개발이 미비한 실정이다. 따라서 본 연구는 화재로 인해 중성화된 철근콘크리트 구조물의 성능저하현상을 파악한 후 내구성 회복을 위하여 침투성 알칼리성부여제의 성능을 평가하고 이용기술을 개발하고자 하였다.
Abstract
Fire breaking out in carbonated reinforcement concrete structures considerably deteriorates the durability of them by propelling carbonation. However, the research and technical development to recover the durability is still in an underdeveloping stage in Korea. Therefore, this research aims to understanding the deteriorated durability of a carbonated structure, evaluating the performance of an impregnating alkalization agent to recover the durability and developing a way of using it.
Key Words: Durability, Carbonation, Impregnating alkalization agent, Re-alkalization
