Engineering Properties of Concrete Mock-up Using Coal Gasification Slag as Fine Aggregate.

석탄가스화 발전슬래그를 잔골재로 사용한 콘크리트 Mock-up 부재의 공학적 특성

In this study, the characteristics of the Mock-up test were reviewed to analyze the applicability of the coal gasification slag (CGS) from the integrated gasification combination Cycle (IGCC) to the concrete fine aggregate. The analysis shows that CGS and crushed sand mix is the best combination of CGS combined with about 50 % of CGS based on the effects of promoting liquidity and strength. This is expected to be a positive factor in securing the strength and flexibility of concrete given the optimal mix of CGS, and may also contribute to the improvement of quality.
