A Study on the Coal Gasification Slag as Fine Aggregate for Concrete - Focus on Chemical Properties -

콘크리트용 잔골재로서 석탄가스화복합발전 슬래그의 활용성 검토 - 화학적 특성을 중심으로 -

This study is a fundamental study to utilize CGS from the IGCC as a fine aggregate for concrete. According to the study, the chemical composition of KS F 2527 was reviewed. The results showed that the KS F 2527 standard was generally satisfied, but the content of the sulfur trioxide(SO₃) exceeded the limit set by the molten slag. The possibility was found to be a fine metal based on chemicals other than sulfur trioxide(SO3).
