Measurement of carbonation depth of concrete in old buildings and experimental evaluation of carbonation degree and CO2 absorption using differential thermal gravimetric analysis
노후 건축물의 콘크리트 탄산화 깊이 측정과 시차열 중량분석을 통한 탄산화도 및 CO2 흡수량 실험적 평가
Abstract
Based on the carbonation depth measurement by the indicator for concrete collected from old structures and the quantitative analysis of Ca(OH)2 and CO2 in the carbonation section before and after the carbonation depth and in the non-carbonation section, the absorbable CO2 amount and carbonation degree measurement result is as follows 1) The carbonation depth of the 40-year-old reinforced concrete structure was measured to be about 22 mm. (basement interior wall, marble finish, strength 30MPa) 2) The amount of CO2 absorbed by the concrete was about 4.3% of the sample weight, and the carbonation degree was estimated to be about 53%.
