Investigation on Carbonation Phenomenon of Type of Use for Concrete Structures aged a decade to fifty years
$10{\sim}50$ 년이 경과한 콘크리트구조물의 사용 용도별 탄산화 현상에 의한 열화도 판정
Abstract
Carburization at concrete structures is being processed independently or compositively and each unique Carburization will appear depending on the condition of circumstance. Therefore, the depletion rate was being estimated at this research for buildings and civil construction structures of different environments and of more than 10 - 60 years old by calculating the depth of carburization and the density of Alkali. As the results of the test, buildings (interior) had a deeper and a faster carburization than civil construction structures being exposed to open air as closer to the shore. And also, concrete structures being used as an underdrain of sewage were proven to have a deeper carburization than utility-pipe conduits or underground tunnels.
콘크리트구조물에서의 탄산화 현상은 단독 또는 복합적으로 작용하고 사용환경의 조건에 따라 각각 상이한 탄산화 현상을 나타나게 된다. 이에 본 연구에서는 사용연수가
