An Analysis of the Characteristics of Changes in Carbonation Components by Environmental Exposure in Deteriorated Building Structures

노후 건축물 구조부별 환경 노출에 따른 탄산화 성분 변화 특성 분석

However, in the case of concrete, there is a concern that carbonation may proceed due to environmental factors. However, in the case of concrete, there is a concern that carbonation may proceed due to environmental factors. Research is steadily underway to prevent carbonation because carbonation decreases durability and increases the risk from disasters. However, there are many cases in which studies related to carbonation have been conducted only with materials in the same space. Therefore, in this study, FT-IR was used to analyze the difference in carbonation components by structural parts of old buildings. As a result, it was confirmed that there was a difference in peak values for each structural part of the building. The difference in peak values was determined to indicate differences in components, so the level of carbonation progress was different, and it is believed that differentiated repair and reinforcement methods will be needed depending on the structure.
