TGA를 이용한 고온 조건에 노출된 시멘트 페이스트 경화체의 질량감소율 특성
Characteristics of Mass Reduction Rate of Cement Paste Hardened to High Temperature Conditions by TGA
- 발행 : 2018.11.16
초록
In this study, TGA analysis of hardened cement paste with fire damage was performed. The mass reduction rate of 600 ℃ specimens was about 22 ~ 25%, and the sample of 800 ℃ showed the mass loss rate of 9 ~ 13%. As the target temperature and hold time increased, the mass reduction rate decreased. As the depth increased, the mass reduction rate decreased.
