- Abstract
- Gamma-C₂S(γ-C₂S)는 실온에서 물과 반응하지만 대기중의 CO₂를 흡수 할 수 있는 물질이다. 실험실에서 합성된 γ-C₂S를 시멘트 모르타르에 CO₂고정 재료로서 혼입하고 28d동안 수중양생시킨 후에 CO₂ 농도5%, 상대습도60%, 온도20℃의 환경에서 촉진탄화시험을 실시하였다. 샘플의 공극구조는 MIP에 의해 재령56일때 분석되었고 공극주조를 Fractal이론에 의해 정량적으로 기술되었다.
Gamma-C₂S(γ-C₂S) is a substance that is difficult to react with water under normal temperature but can absorb a large amount of CO₂ in the air. The addition of γ-C₂S to cementitious materials through the curing of CO₂ can improve the pore structure and improve the durability of the material. In this study Synthesized γ-C₂S was added to the cement mortar, after water curing for 1month, accelerated carbonation test was experimented. After 28d accelerated carbonation test, pore structure will be detected by MIP. Based on the MIP result, following the calculation method of Fractal theory, the pore structure will be quantitative described.
